I have an Access front end sitting on an MSSQL backend. I've a order form that has been working great for a couple of years now (did the conversion from access backend two years ago). Just recently however, line items will display but will not add to the total on the invoice. We've seen this happen with various scenarios, many different order types, different stores, different everything. At first I thought it to be a corruption issue, so we've since moved to having a clean build of the MDE and copying the fresh copy to the local machines each time someone logs in. Additionally, the invoice can be reprinted immediately and it will work fine. We've not been able to recreate this issue on demand, and the people running it aren't saavy enough to give me any more details than to show me the invoice that didn't print. Any thoughts?
