I have a form that is intended to allow the user to authorize payment. User receives numerous requests through a query reading an Is Null field. The button is to fill the Is Null field on the multiple records with the user's name.
I have seen this in previous inquiries in the archives, but cannot get the syntax or command right in the 'On Click' property. Any help?

Not enough detail here to help you - email me and we can discuss it.
