Ok. I'm making progress.

I tried: =IF(1, "FormatHidden", "FormatHidden") to try to force hiding in all conditions. All that happens is columns A,B&C show blank and the rest of the columns are unaffected.

Even if I could get the entire line to show blank would I not simply see a lot of blank lines on my printed report?

Is the "FormatHidden" style supposed to suppress printing of the line? I can't find in the manual where it describes what this style specifically means.

Thanks again.
