I am preparing a form in Adobe Acrobat 9, and I need to perform a calculation that would require an "if-else" statement (I think!)

If the user enters a GST number (GSTNum), then I want the subtotal (TotalDues1) multiplied by the GST rate (GSTRate1). This calculation will take place in the field "Text4"

This is what I have, but it doesn't seem to be working:

var f=this.getField("GSTNum");

if (f.value<=0){event.value=0}
else{event.value=TotalDues1*GSTRate;}

I am very green to Javascript, so would appreciate any help!!

Thanks,
Tracy

And what is the value of the variable GSTRate and the TotalDues1 set?

If they are fields, you need to get their field vlaues.

GSTRate1 is a field, manual entry of the rate will be entered in the form. TotalDues1 is a calculation field, which is the subtotal of other cells. It is a hidden field, only for calculation purposes.

You need to get the fields and values before you can use them:

// get the GST Num field object
var oGSTNum = this.getField("GSTNum");
// get the Total Dues field object
var oTotlaDues = this.getField("TotalDues1");
// get the GSTRate field object
var oGSTRate = this.getField("GSTRate1");

if (oGSTNum.value <= 0){
// if GSTNum less than or equal to zero the event value is zero
event.value = 0;
} else {
// else the event value is total dues times GST rate
event.value = oTotalDues.value * oGSTRate.value;
}
