Write formula in VBA Excel

Question

I have troubles with writing formula in Excel VBA.

Sub Macro()
  valueA1 = Range("A1").Value
  Range("C1").Formula = "=RC[-1]*" & valueA1
End Sub

At the end I want formula in cell C1 to be written as =B1*0,5 , if value in B1 is 0,5 .

Thaks for the help!

Excel doesn't like foreign languages. You will need to use FormulaR1C1Local :

Range("C1").FormulaR1C1Local = "=RC[-1]+" & valueA1

or maybe

Range("C1").FormulaR1C1Local = "=RC[-1]*" & valueA1

if you are trying to multiply B1*A1. (Your question says multiply, your code says add.)

That should cause it to accept "0,5" as a valid number.
