Javascript only works for "easy" numbers (and multiplying error)

Question

HIi Everyone,
I have a scripting problem.  I used javascript to do some division and subtraction, but it only works some of the time in the second half of my form.  What I mean is, if I'm using a nice even number like 100-the calculations are correct, but if I use 415.75, it calculates, but not correctly.  (I actually also have that problem with some multiplying also???)  It's very weird.  And it only seems to be this particular form.
I can e-mail the form if that will help.  I'd appreciated any help you can give me.
Thanks,
Valerie

Answer 1

Sure.  The form looks like this: (Field Names are in quotes.)
1. Total Amount of Third Party Recovery      "total third"
2. Accrued Compensation Lien                   "accrued"   (I clicked in calculations and just clicked "value is the sum of the following: and then clicked the field
     a. "indemnity benefits"                                             names of a and b.)
     b. "expenses of medical"
3. Expenses of Recovery                             "recovery expenses"
4. Balance of Recovery                              "balance"  (Its supposed to be #1minus #2)  I used this script:
                                                                 this.getField("balance").value = thisgetField("totalthird").value - this.getField("accrued").value;
HiddenLockedField "percent" (The content is set to 100.)
5. Lien Expenses Reimbursement Rate          "5"   (#2 divided by #1 * 100)   I used this script:
                                                                   event.value = ""
                                                                   var accrued = getField("accrued").value;
                                                                   var totalthird = getField("totalthird").value;
                                                                   var percent = getField("percent").value;
                                                                   if(totalthird!null && total third!=0)
                                                                   {event.value = accrued / totalthird * percent;}
6. Expenses Attributable to Lien                    "attribute"    (Supposed to be #3 times #5.)  I went to calculations, anc clicked on, "value is the product
                                                                     of the following" and checked "recovery expenses" and "5".
7. Net Lien                                                   "netlien"   (Supposed to be #2-#6) I used this script:
                                                                   this.getField("netlien").value = this.getField("accrued").value - this.getField("attribute").value;
8. Reimbursement Rate of Future Lia.             "rate" (Supposed to be #3 divided by #1 * 100.) I used this script:
                                                                     event.value = "";
                                                                     var recoveryexpenses = getField("recoveryexpenses").value;
                                                                     var totalthird = getField("totalthird").value;
                                                                     var percent = getField("percent").value;
                                                                     if (totalthird!=null && totalthird!=0)   
                                                                     {event.value = (recoveryexpenses / totalthird) * perent;}
