I put the WAIT window command in the Change Event and I received the same error as before. I must not have this stuff laid out correctly. Did I have to create any special PEMS for any of these objects? When I queried for the contents of VALUE the debugger told me that it could not be evaluated. When I look at the object hierarchy I have a FORM, a PageFrame and 2 scrollbars VERTSCROLL and HORIZSCROLL. Am I missing anything?
