>I have dealt with this by creating a formula field and using IIF to set the label value to blank if the text field value is null. I didn't have much luck with the Suppress on labels, either.

Hi Linda,

I found that it was my own fault - I forgot to include this field in the resultset in the SP. In other words, I had the field defined in DataSet, but I didn't have this field in my SP.

Once I corrected this problem, the Suppress worked OK for this label.
