"Invalid Use Of Null" using CDate

Hi All,

I have a date/time field in a table which is converted within a query from a string value via the following:

New Date Field: Int(CDate([Original Date Field]))

The problem is, I cannot view the query in design view if any records do not have data within the date field -- I get a "Invalid Use Of Null" error message.  This field will not always contain data, therefore, I need some way to work around this.

Suggestions?

Thanks,
Ed

Alternatively, you can avoid the IIF function by using:
     Format(Nz([Original Date Field], ""), "mm/dd/yy")

Jokra, will your function convert my date/time field ...or leave it as a string?

Folks, I've tried all suggestions -- and I do not get the error anymore.  However, the sort order is incorrect...it appears that the field is sorting like a string field rather than a date field.
