Best workaround to display a tooltip like messages data entry form

[Lucinda_Mason]

New users are presented an “Add New User” form after opening my app. It captures their USEREMAIL() and has fields for pertinent info that I store in a USERS table.

One field needs very detailed explanation. I don’t like the look of using a long Description to label that field. Every other field has one or two word Display Names.

Is there any way to make a message pop up when the user clicks in that field and display a message?

It needs to be attached to just that one field, not to the whole form.

Thanks for any advice.
