Daily bar formula on intraday Radarscreen?

["jbclem1" <jbclem1@xxxxxxxxxxx>]

I'm using a simple formula, Vol/PrevVol on some RadarScreen pages.  It works fine on the page where
the datacompression is set to Daily.  But on the page where datacompression is set to 3min, this
formula calculates using the previous 3min bars volume.  I need it to use the previous days volume.

I added "if datacompression=2 then begin" to the formula used on the 3min bar page, but that just
resulted in blank cells.  Would someone show me how to write the formula so that it would refer back
to the previous days volume and still work on a page where all symbols are set to a datacompression
of 3min.

Thanks,

John
