Operations Multiply or Subtract two Textfields

General
#1

Hi.

I know that this is very stupid question that some has made,but here I go:

How did I plus,multiply or subtract the values of two textfields?

Thanks

#2 
x=val(textfield1.text)*val(textfield2.text)

Yeah I know thats the “old” framework… but it still works, and I’ll let someone else post the “verbose” version

I got error

There is more than one item with this name and it’s not clear to which this refers.
x =val(textfield1.text) * val(textfield2.text)

Note: Use CDbl for values coming from the user (per the docs!)

Break it down

dim a, b, x as double
a = val(textfield1.text)
b = val(textfield2.text)
x = a * b

Where does the error appear?
