I'm trying to hide/display fields, based on values that come back from the report's main query. Is it possible to find (and use) a field's X coordinate in an expression? So, if the report query returns $F{START_POSITION} and $F{END_POSITION} as 20 and 40 respectively, I want to display the fields that are between X=20 and X=40 and hide all the others. The X value is available via the properties pane for all fields, but how do I reference it in an expression? Can that be done? Paul
