I have an asp webform that other users can fill in. For one field in that form (call it 'z'). I have an array (call it 'y') which holds all the values 'z' cannot be and I have a function (call it 'f') which needs to be launched if the value of 'z' appears in 'y'.
However, I am missing the bit that actually checks 'z' again the values in 'y' and launches 'f' if needed. I've done countless Google searches and come up with nothing.
