Performing subtraction on 2 fields to fill another
I am so frustrate with Access. This is so simple in Lotus Approach. Any one
help me? I have 2 date fields and I want to calculate the number of days and have the result appear in a 3rd field. The expression builder is not showing the tables in my DB, and so I cannot use that method! Why doesn't Mocrosoft just add a calculated field like Approach has!

Look at the DateDiff function in the Help file.

It is very simple to do this (in a query). The results of such calculations do not belong in tables. -- Rick Brandt, Microsoft Access MVP Email (as appropriate) to... RBrandt at Hunter dot com

Tried that, steve, but it just wont take it. Like I said, the table fields
are not even showing up in the expression builder. Is there something that has to be turned on? Diane "Steve" wrote: Look at the DateDiff function in the Help file.

The expression builder is not showing the tables in my DB, and so I cannot use that method! Why doesn't Mocrosoft just add a calculated field like Approach has! Access is NOT a flawed implemenation of Approach. It is a different program, with different conventions! If you insist on treating it as a version of Approach you will indeed be frustrated; if you meet it on its own terms, you will find that it does everything that Approach can do - but *differently*. You may need to "unlearn" some things! That said: create a Query based on the table. Include the two date fields, and any other information that you would like to see. In a vacant Field cell type DaysBetween: DateDiff("d", [firstdatefield], [seconddatefield]) using whatever fieldname you would like. you can now base a Form or Report on this query and see the result you want. Note that tables (in Access, if not in Approach) are designed for data storage - not for calculations, and not for data presentation or interaction either. -- John W. Vinson [MVP]

Diane,
See John Vinson's response in this thread. Suggest you still look at the DateDiff function in the Help file. Steve "Guanamom" wrote in message ... Tried that, steve, but it just wont take it.
