Possible to show/hide sections in a table?

Question

Hello all,
First post here. I've only started using LiveCycle Designer a few weeks ago, never knowing that it came with my Acrobat. I've been busy converting forms we use in our business into pdf versions that can be filled, and created some with simple scripting etc.  Anyway my most ambitious effort to date is to create a gross payroll calculator in which I would enter the total hours worked for each employee and the gross payroll is calculated. The calculations I have no issue with.
I am using a hidden "config" subform (thanks to kingphysh for your easy and simple example!) to store the employee names and payrates and the department they work in.
My main form, the one on which I am entering total time for each employee, consists of a table with a section for each department. Thus I can put all employees in a department in one section of the table and then easily do subtotals by department etc.
Table1
Table1.Section1
      Dept. Name | Emp. Name | Pay Rate | Total Hrs | Gross Pay|  <-- this would be one row in the section     
Table1.Section2
      Dept. Name | Emp. Name | Pay Rate | Total Hrs | Gross Pay|
Table1.Section3
      Dept. Name | Emp. Name | Pay Rate | Total Hrs | Gross Pay|
and so on. Each section also has a footer row for subtotals.
This form will be used at various physical locations and not every location will have all departments. Thus I want the table to show only those sections for which the corresponding departments exist based on a selection (checkbox) that is on the hidden config page.
Its not so much the actual scripting thats a problem, but where to put the script. Should I use a Table1 event or the checkbox event? I've tried both but neither works as desired. Or should I use an event for the individual rows in the section itself?
Any pointers and suggestions will be greatly appreciated!
Harry.

Niall,
Many thanks for all your help. With the examples you provided, I have been able to almost finish the form and learned a little bit along the way too.
There are a couple of things still vexing me though.
My form's hierarchy is as follows:
page1 (flowed)
     - wrapper (flowed)
          - form1  (positioned)  <-- sub-form (form on which data is entered and calculation results are displayed_
               - table1
                    -HEADER
                    -Section1 - bodyrow
                                   - section1 footer
                    -Section2 - bodyrow
                                    - section2 footer
                    -FOOTER
          - config   (positioned) <--  sub-form (normally hidden "config" form which stores employee data - accessed by password
               - table1
The sub-form form1 contains a table with six sections. Each section represents one department and has  body rows and a footer row for subtotals.
the number of body rows in each section can vary with the number of employees in the department.
I have two issues remaining with the form and it will be done. Hopefully you will be able to point me in the right direction.
1. Pagination - in the form, I have set page1 to "flowed". wrapper is also flowed. form1 is positioned.
     I would like to be able to set it so that if any section is going to be split, it would go onto the next page.
     The header should be repeated in each page. Each section footer should be with the section, and the Table footer should be on the last page.
2. Column Subtotals
     I have set the form to be as general purpose as possible. Thus it can take time totals in either decimal or HH:MM format. I am having trouble adding columns of time totals in HH:MM format.
For example, given 3 time totals (all are in text fields):
10:35
15:59
03:24
I would thing the best way to do this is to parse the strings and add the minutes and hrs separately and then depending on the total of the minutes, use the floor and mod functions to get the correct total. I just can't get it to add the columns at all.
This is the code I am using to add the column:
if (_FD.count gt 0) then   //make sure at least one body row exists in this section
for i = 1 upto (_FD.count) do
mins = Sum(Right (FD[i].fdr_tot[i], 2))        // FD is the row and fdr_tot is the cell in the row which is to be included in the calc.
hrs = Sum(Left (FD[i].fdr_tot[i], (Len (FD[i].fdr_tot[i]) - 3)))
endfor
endif
I've tried using the code below as well to no avail.
mins = Sum(Right (FD[*].fdr_tot[*], 2))
hrs = Sum(Left (FD[*].fdr_tot[*], (Len (FD[*].fdr_tot[*]) - 3)))
Any suggestions will be greatly appreciated.
Thanks.
