Is it possible to leave a "date/time" record blank? 'cause when I do so there's always an error on the ASP webpage.

Well not knowing what you are really talking about I am just going to assume. If you have an access database with a date/time field you just need to make sure that in the design view it says 'No' to the 'Required' dropdown box. Then you can leave it blank. If you still get an error, there is a prob in your sqlscript, guessing as there might be a value you entered it into a variable to insert into the db, thus when someone leaves it blank it bombs as it tries to insert "Nothing" instead of leaving it NULL

It's actually an SQL Database. I'm getting this error when I trie to open the ASP page.

Microsoft VBScript runtime error '800a000d'

Type mismatch: 'FormatDateTime'

/asp/EersteElftal/spelers.asp, line 116

I don't get the error when I fill in a date in the date/time field in the database, just when I leave one blank. These are the options I have when I want to add a column:

Ordinal 6
Name < name=fname>
Data type < =:onFieldChange(this.options[this.edIndex].value); name=> Date/Time Long Integer Text AutoNumber Memo Currency Binary Byte Decimal Double Integer Single Boolean Replication ID
Nullable < = value=-1 name=nullable>
Max. length < size=5 name=length>
Default Value < name=default>
Description < name=deion>
Indexed < name=indexed> No Yes, allow duplicates Yes, unique index
< class= =submit value=Update name=submit>

Its not the database causing the problem. Its your code.

I'm guessing you are trying to use the 'FormatDateTime' function (as it says in your error message), however you can't format a 'NULL' entry! Hence the error message.

In other words, you need to check to see if it's a null entry (using ISNULL) before you try to FormatDateTime()

Cheers,
Andrew
