In terms of the query, it would not matter since you still need to get the values in the controls whether they are bound or unbound to do the append to the asset usage table..Another thought about that. Could I add two new fields in the Assets table for "UpdateUsage" and "UpdateUsageDate" ? Then I could bound the text boxes couldn't I? And wouldn't that also make it easier to run an append query on?
I would also worry about normalization since you technically would be violating normalization rules.
