Never been good at RegEx.

Goal is to test a string to make sure it only has legal characters for a simple filename. (A-Z, a-z 0-9 and _ - dashes preferable)

I know that \w works for a-z A-Z and 0-9 and _ but I'd want dashes as valid too. No periods. No spaces. No other random characters.

No idea how to test a variable for the condition in Lasso either.

Thanks
Marc Pope
