    Hello I Am building a windows form application that accept an expression involving two variables and two numerical values for the variables through a text box. the App is then suppose to display a functional value for the user. I tried everything possible but keep getting error "input string was not in correct format" Thanks in advance for your help (anyone).

      Most likely you are trying to convert some characters into a numeric, but it contains letters or special characters. However, since you have not shown us your code, or the data that it is trying to access, that is just a guess.

        you're right what I want the program to do is accept an expression involving two variables from the user together with values. the program is then suppose to return a functional value as double

          That sounds simple enough.
