[AccessD] Required Field in Function

I removed the Cancel = True, added "Else" after the MsgBox, and moved the
End If to the bottom of the code. But I still receive the RunTime Error 424
Object Required on the If IsNull ... code. Am I missing something else? What
would stop the code from running and what is causing the error?
 
If IsNull(xlsBPS.AssetID) Then
   MsgBox "Asset ID must be completed before downloading"
Else
.......
End If
End If

Your test may well be ok but all you're doinmg is setting Cancel=True; you
still carry on and execute the queries. The query execution needs to be on
an Else so that it does not run if the IsNull test is True. Setting
Cancel=True does not stop subsequent code.

Subject: [AccessD] Required Field in Function

 I have a function (code below) that is used to append data from a linked
Excel file (xlsBPS). The Excel file is linked to the database as a table.
 There is a column in the Excel file named AssetID - this is a required
field in the database. Yesterday when the user ran the append code the
AssetID was blank in one of the records in the xlsBPS file. This caused all
the records to move up one. For example:
 
 Record 1: AssetID =
             Description: This one
 
 Record 2: AssetID = ABC
             Description: My Name
 
 The results after the append code ran were:
 
 Record 1: AssetID  = ABC
             Description: This one
 
What can I add to the function to check for null fields to ensure the
AssetID is completed, if not, the code does not run? I tried adding a check
(where I added the ***** in the code, but I receive the error, RunTime 424,
Object Required.
