Nick - I found the problem. When I looked in the PEM , I noticed that GHL was located between the form and grid1 levels. (does this make sense?) I deleted that instance of GHL, and inserted a new one and the form worked fine. Thanks again for you help.

>>>I'm using Nick Neklioudov's grid highlighter class in a form. The highlighter work fine, however when I exit the form, I get an error that says: Property GRID1 is not found. Debug shows that this error is occurring in the destroy event of the Grid Highlighter class. Any ideas on what I'm doing wrong?
>>>Thanks!
