How do I fill and show/hide a series of text boxes based on checkboxes?

Question

I have a series of checkboxes on a form (each of which requires some additional information to be entered) and a series of text boxes further down the page to house any necessary detailed information. 
I have hidden the detail fields and coded the form so that for each of these checkboxes that is checked a row of detail text boxes appears with the checkbox title in the activiy type field, and if a checkbox is subsequently un-checked the last row of detail text boxes is hidden. 
The problem with this is that if the user unchecks any box other than the most recently checked one the data for the option they just unchecked still shows, but the data for the last option they selected does not. 
Does anyone have a solution that would make sure the detail fields for the boxes that are checked is displayed in the detail text boxes that are showing when a checkbox is unchecked, regardless of the order in which the boxes are checked/unchecked?
This is what my form looks like, with the example where Cash Withdrawals is unchecked but appears in the detail and Remote Deposit Capture is checked but was hidden with the last line:
The detail groups are named Act1.child, Act2.child, etc. where the description field (filled in the example above) is Act1.type, Act2.type, etc.
Here is the script I'm using on the checkboxes to achieve what I'm getting now:
var useSet = this.getField("Set").value;
var clrSet = this.getField("Clr").value;
var useType = useSet + ".type";
var clrType = clrSet + ".type";
if (this.getField("CheckboxName").value != "Off") {
    this.getField(useType).value = "Check Box Desription";
    this.getField(useSet).display = display.visible;
else if (this.getField("CheckboxName").value == "Off") {
    this.getField(clrType).value = "";
    this.getField(clrSet).display = display.hidden;
and here is the script for the hidden boxes that determine what sets are filled and what sets are cleared and hidden:
Custom Calculation Script for "Set":
var sOne = this.getField("Act1.type").value.length;
var sTwo = this.getField("Act2.type").value.length;
var sThr = this.getField("Act3.type").value.length;
var sFour = this.getField("Act4.type").value.length;
var sFive = this.getField("Act5.type").value.length;
var sSix = this.getField("Act6.type").value.length;
var sSev = this.getField("Act7.type").value.length;
if (sOne == 0) {event.value = "Act1"}
else if (sTwo == 0) {event.value = "Act2"}
else if (sThr == 0) {event.value = "Act3"}
else if (sFour == 0) {event.value = "Act4"}
else if (sFive == 0) {event.value = "Act5"}
else if (sSix == 0) {event.value = "Act6"}
else {event.value = "Act7"}
Custom Calculation Value for "Clr":
var cOne = this.getField("Act1.type").value.length;
var cTwo = this.getField("Act2.type").value.length;
var cThr = this.getField("Act3.type").value.length;
var cFour = this.getField("Act4.type").value.length;
var cFive = this.getField("Act5.type").value.length;
var cSix = this.getField("Act6.type").value.length;
var cSev = this.getField("Act7.type").value.length;
if (cSev != 0) {event.value = "Act7"}
else if (cSix != 0) {event.value = "Act6"}
else if (cFive != 0) {event.value = "Act5"}
else if (cFour != 0) {event.value = "Act4"}
else if (cThr != 0) {event.value = "Act3"}
else if (cTwo != 0) {event.value = "Act2"}
else {event.value = "Act1"}

Hi Andi,
Please consider the following “solution” too.
Preliminaries
An indicator can be considered a variable in JavaScript.
If P is an indicator, m(P) refers to the value of the indicator.
Data for Control
There are four checkboxes: C0, C1, C2 and C3.
There is an indicator for each checkbox: CP0, CP1, CP2 and CP3.
If checkbox Ci is checked then checkbox indicator CPi has the value i+1; in other words, m(CPn) = i+1. If checkbox Ci is not checked then checkbox indicator CPi has the value 0; in other words, m(CPn) = 0.
There are four sets of detail fields: A0, A1, A2 and A3.
There is a detail fields indicator for each detail fields: AP0, AP1, AP2 and AP3. If detail fields Ak have the details for the checked checkbox Ci then APk has the value i+1; in other words, m(APk) = i+1. If detail fields Ak do not have any details for any of the checked or unchecked checkbox then APk has the value 0; in other words, m(APk) = 0.
The sets of detail fields are organized in sequence. The “top” or “first” set is AP0. It is followed by AP1. Then followed by AP2. The “bottom” or “last” set is AP3.
Consider an example with one checkbox selected. In this case m(CP2) = 3; m(AP0) = 3; m(CPi) = 0 for i=0, 1, 3; and m(APk) = 0 for k=0, 1, 3. See the following diagram too (see Figure 1).
Events, Processes and Additional Data for Control
Computation begins when a user event is captured by the system (such as a mouse up event in an AcroForm field like a button or a checkbox).
Checking Process
If a checkbox is checked (TNj), it is noted with an indicator (P0).
Shift Process
Given a noted checkbox, the search for a candidate set of detail fields to use for the noted checkbox begins.
The first candidate is the bottom of the sequence. This is also the current candidate, k. Thus k=3.
The current candidate is remembered by marking (TSk,j) the detail fields indicator (APk).
If k=0 then the shift process ends and the current candidate is the candidate.
If k > 0 and m(APk-1) = 0, the current candidate becomes APk-1 and step 8c is repeated.
If k > 0 and m(APk-1) != 0, then the shift process ends and the current candidate is the candidate.
Unchecking Process
If m(CPi) != 0 and m(CPi) = m(APk), then the checkbox can be unchecked (TRk,i).
Shift Process
If m(APk)=0 and m(APk+1) > 0 then shift (TSk,m(APk+1)). At the end of this shift, m(APk) > 0 and m(APk+1) = 0. Let k = k + 1.
If m(APk+1)>0 then repeat 9a. If m(APk+1)=0 then the shifting process ends.
Last Events and Proceses
Details fields can be initialized (TIk,j) and displayed (TDk,j) or cleared (TCk,j) and hidden (THk,j). These actions depend only on m(APk). However it would be a good idea to trigger these functions right after a shift process ends and on affected details fields.
