	I have added a date/time field and text box in the report I am working on. I would like to suppress the text box when there is no date/time. I have tried the format editor - common tab - suppress - and used a formular to suppress if there is no date. It does not work! Yet no date is listed on the date field. ??

	the supression formula would be something like: isnull({table.datetime}) that should do it HTH

	are these all on the same detail row or are you doing summary level checking? is it really a datetime field or a string that is formatted like datetime? Edited by DBlank - 19 Sep 2012 at 10:19am

	Hi.. In suppress formula editor.. On top middle there is drop down box, choose Default values for Null and make the following change in your formula : isnull(table.field) or {table.field} = " "
	Thanks, Sastry

	I have it in the group editor and it is a datetime field. There must be some kind of default date but when I look in the table that the information is coming from it's blank. I can not believe something that I thought would be so easy ends up being so difficult!

	I did the formula and it says that there is an error in the formula - i highlights "" and says a datetime is required here.

	What do you mean by "I have it in the *group editor*'?

	Sorry...I meant I have it in the group header not in the detail section of the report.

	The formula you wrote evaluates per row (detail section). Since you are palcing it in a group header it is only evaluating for the first row in the group. try to do some trouble shooting make a formula field as lockwelle suggested usingh isnull({table.datetime}) place it on the detail section it should return True (if the fiel sis null) or False (if the field has a value). Is this working as you expect?
