dim b as double
dim c as double

c = double(Text1.text)
result = (c * b) / (c + b)

man i tried that double(Text1.Text) but it doesn't seem to be recognised by the compiler.

Try:

c = CDbl(Val(Text1.text))

or

c = CDbl(Text1.text)

The Val() function just converts text1.text to a number (or tries to at least), but it may not be necessary if you only have numbers (i.e. Val could convert A1 to 1)
