How To Crash Access

It seems to be quite simple really. Make a form for Orders and add a subform for Order items. Write some VB code to chage values on the Order form when an Order item is added or amended. Add a "Find" dropdown to the Order form to find particular Order numbers.

Run the form and add/amend orders and items. This will work OK. Move to the next or subsequent order using the "Next" button. Add/Amend again - no problem. Drop down the "Find" control, select an order and the correct order comes up on the form. Amend an item. As the code attempts to change a text box on the Order form Access crashes.

The same code (to add up the items, take off discount and add on tax) can be run after a "Find" by changing a "Discount %" text box on the Order form and this works OK. Perhaps the Order form needs to be in focus for the code to work but I cannot see why this should be so.

In fact you don't actually need the "Find" dropdown. Any code that moves to another Order record programatically will cause Access to crash when an item is added/edited subsequently.

Making it crash is simple but stopping it has cost me a couple of days of frustation. Has anybody any ideas?
