>I have a grid based on a filtered table. In my form I want to have a textbox that I as the admin. can type in a variable for the filter expression and the grid refresh with to new records. I can't seem to get this to work.

lcFilter = "MyField='"+thisform.txtBox.value+"'"
set filter to &lcFilter

It could be better to use views or SET KEY command. Grid and filters don't like each other... :)
