Hi Randy,
>How can I keep my user from unchecking the checkbox when they enter through it. What I would like to see they can place a value in the checkbox by the spacebar or mouse.
Do you mean when the user hits enter do not Check? Put this in your InterActive Change event:
if lastkey() = 13
This.Value = iif(This.Value = 1, 0, 1)
endif
Does this help?
