Firstly, what is your Range Variable? as that looks like that could be the cause of your error.
If you want to just retrieve the numbers from the Var you can use an assign like below: VarRPS = System.Text.RegularExpressions.Regex.Replace(VarRPS ,“\D”,“”)

BTW: is is recommended to not have spaces within the variable name. Its not the rootcause of your issue, however do a renaming as well.
