I get an error, a red line below the variable intAge in the if-statement in the code. It says the variable is local, but how could it be local when it is declared in the beginning of the code? Does it have to do with the Try/Catch part? The reason why my code looks like it does, is just beacuse I have to use a Try/Catch in the code for this task. Preciate some suggestions to solve this in a similiar and correct way? Thanks!

int intAge;

        try
        {
            intAge = int.Parse(age);
        }
        catch (Exception)
        {
            MessageBox.Show("Enter an age in numbers!","Error!");
        }
        finally
        {

        }
        // Check input
        if (intAge < 1)
        {
            inputOk = false;
            errorMessage = "Please enter 1 or higher!";
        }
