Crystal Reports – Problems when encounters a NULL

Hello –
I am very new to crystal reports and I am having problems figuring out why my entire report appears blank (except for field headings) when it encounters a NULL value in a field that is linked to another table.

I’ve checked the “Convert Database NULL values to Default” option under General Settings in Report Options but that does not seem to handle this problem.

Like I mentioned this problem is specific only to fields that are linked to other tables. I’ve also tried using an unbound string, so that I can try using an if,then,else logic along with the isNULL() function. – No Luck

Has anyone else bumped into this crazyness ?

Thank you,
Shawn Owens
