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?

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. |

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?

It runs false on all, even the ones that have no date/time. Is there a way to find out what the default date is? I don't know if this helps but I have an SQL server and the date field that this table is getting information from is a drop down calandar. Thank you for you help!! I think I am going to give up! |

try
table.datefield = date(1900,1,1)
and see if you get any True values returned

what number do you get on the 'blank' rows when you do this
datediff('d',table.datefield,currentdate)

| you could also try totext({table.field}, "MM/dd/yyyy"} |

| When I did the totext I got 12/31/-471 |

interesting
i did not think negative year values were allowed...
It wont accept date(-471,12,31) as a value so maybe try
table.datefield < date(1900,1,1)
