I'm having a problem doing anything but adding. The attached
code works if it's addition (+), but if I try subtracting (-),
dividing (/) or multiplying (*), I get the following error. I can
place the form for you to see, but all it amounts to is two input
text fields, a submit button and a result/answer dynamic field.
Error: Type mismatch in assignment statement: found Number
where String is required.
