Text box with Add/Delete only

[velcrowe]

Is there any way that I can restrict a text box entry from being changed? I am working on a tracking system and presently can capture when a text field entry is added or deleted. I can't capture when a text field entry is overwritten. Therefore I only want the user to delete the present entry and then add a new entry in the text box. Is this restriction possible for a text box?

Overwritten is the same as deleted then added isnt it? or are u talking about the whole record being deleted then a new one being added?

Yes, overwritten meaing deleted then added. I don't want the whole record deleted. If a user is replacing an item with a specific equipment #, I can capture when the user deletes or adds the equipment #. However, when I type over an existing equipment number I cannot capture that event as a delete on "exact date" and then added on "exact date."

have u tried the after update option..

I am using the after update event to capture the add or delete. I just cannot get how to capture that change in code. For instance 2 is overwritten by 3. I would like to capture that change and record it as "item 2 exchanged by item 3." Is there any code that you can think of.
