I have been unable to resolve my issue.
I followed the instructions in the original post.
"The field should be a drop-down list."
I created a standard drop-down list as one of my questions.
I then populated the values of the drop-down list as indicated in original instructions.
Ensuring to use the semi colon to separate the email address from the display label.
The next step was to text the form layout to ensure it displayed only the label and not the value.
The display test reviled all the text was displayed in each drop-down field including the semi colon.
I also added the form into a page to ensure it wasn't some sort of configuration view I was seeing but it still displays all the characters in the selection including the semi colon.
I have searched through all related posts and google to see if I have missed some step but it appears to be very simple.
The problem is I want to hide the actual email address as the original post seems to indicate.
Any further assistance would be greatly appreciated.
