Unknown Date Function

I have a field in my database called "ActionDate", in the design of the table the default value I have set to "Date()" - I want the field to automatically populate with todays date when a record is created.

Words great on my computer but when I try to run the application on another computer in the office it comes up with this error: "Unknown function 'Date' in validation expression or default value on "tblActions.ActionDate"

What is the better way to assign today's date to a field upon record creation to avoid this issue?

gcgcit,

Please go to the VB Editor, and select Tools|References from the menu.  Are any listed as missing?

The Date() function is standard; when you see that error with a standard function, it is often a symptom of a broken reference.

You need to go to menu References and resolve any reference marked MISSING.

Actually, just spoke with tester when I went to check the references on their machine and it's when they are trying to access the software through Citrix not straight through their machine.  All our machines seem fine.

What reference would hold the "Date" function?  So I can get the Citrix administrator to look into it.

I just got the administrator to open access in Citrix.  See attached photos for the references.

What should I do?

What version of Access?
All updates installed (Office, Widows, Citrix...)
I am running two db's over Citrix and have not had issues with this error...

<just spoke with tester when I went to check the references on their machine and...>
And..., It is still not clear if any were marked "MISSING"

That seems OK.
Then remove one, press OK, add it back, press OK. That should do it.

Anyone except the two top references which are non-removable.
It is just to "stirr the pot" ...

"What is the better way to assign today's date to a field upon record creation to avoid this issue?"

Use the Form Before Insert event, as follows:

Private Sub Form_BeforeInsert (Cancel As Integer)

   Me.ActionDate = Date()

End Sub

I avoid setting Default Values at the Table level because 1) I've seen them get blown out too many times due to corruption and what not and 2) ... When you do this, then on your form when you go to the New Record position ... you see already a (in this example) a Date value in a text box - even though the new record has not actually been created.  A lot of times, this confuses users ... making it look like there is already a record.

Using the BI event, you avoid this. The control will not populate until the first Bound field on the Form is edited.

However ... IF ... you actually do have a Reference issue here, this will not solve that problem.

In the end it wasn't a reference issue.  I replaced default values at table level with form before insert as per DatabaseMX's suggestion and voila - it works now on citrix!

Thank you for the additional information on the hazards of table level default values etc.
