Hi,
I m hoping that someone in this forum might have encountered this situation and already got help on 'how-to.'.
I have a textbox with email addresses separated by semi colons. I also have a drop down list box with those peoples' userid. What I m trying to validate is if username() doesn't match any of the drop down list box items, then deactivate a button to submit. I don't know if its simple to achieve or a custom code is needed.
I want to do it using rules if possible. Please let me know. TIA.
