How would I do the opposite of 'variable = CInt(Val(txtInput.Text))', like if you enter a number it would return a value of 0

    Simple way to check for a number....

    [code]
    If Not IsNumeric(txtInput.Text) Then
    'it is not a number
    variable = .....
    End if[/code]

    If you want something more complex that can account for specific special characters and such, you need to learn how to write a Regular Expression, google it and you will find plenty of examples.
