Jerry,

Your second form must be modal, and whatever you return in the unload event will be returned to the caller, so your code will look like this:

do form payment with total_invoice to loMoreInfo && total_invoice must be modal

&& Now you have
with loMoreInfo 
  .Cash
  .CreditCard
  .CardNumber
  * etc
endwith

Now, let's say you want to return multiple values, then the easiest way is to use an object, so in your unload of total_invoice form you put something like:

loInfo = createobject('Empty')
addproperty(loInfo, 'cash', lnAmount) && Assuming you assigned lnAmount with the value you want to return
addproperty(loInfo, 'creditcard', lcCreditCard) && Same
addproperty(loInfo, 'cardnumber', lcCardNumber) && Same
addproperty(loInfo, 'cardholder', lcCardHolder) && Same
addproperty(loInfo, 'debitcard'), lcDebitCard) && Same

return loInfo

If the data comes from one table, instead for createobject empty and all add properties, you can use SCATTER NAME loInfo
