Javascript - Check field value against an array

[T_Virus]

Hi All,

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.

Can anyone help?

Don't worry. Finally found it during a search ... literally seconds after posting here. It's always the way!
