    RunTime Error 94 - Invalid Use of NULL

    Hi!

    Have just loaded 4.0.4 (from 3.5.1) and was asked to upgrade database from v10 to v15

    Got the following error ... RunTime Error 94 - Invalid Use of NULL

    SCM and PC Till wont run as want to upgrade database again, except this time error ...

    "DiscountReceived" field already exists in "ReceiptDetails"

    Can you suggest where I need to look for an error in my existing mdb file?

    Ta!

    ADDED - I've gone back to 3.5.1 and restored the db from backup ... all back to normal.  Awaiting response before I upgrade again

    Ta! (again)

    Hi Jimmy.

    Would you be prepared to email us your mdb file, so we can see where its throwing an error?

    It may be an error in the conversion, or it may be corruption/invalid data in the database which we need to put so extra code in to deal with.
