Yes - the GHL has to be at the same level as the grid is.

>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.

Debug shows that this error is occurring in the destroy event of the Grid Highlighter class. Any ideas on what I'm doing wrong?
