Thanks in advance for your help :)
I thought I had followed all instructions in the seminar very closely with the exception of adding a few extra fields to customise the form to our requirements.

Everything works perfectly, I can check items in and out as expected. However, if I check an item out to one customer then use the record selector at the bottom of the form and proceed to any other record, that customers details default over to any other record where the item is marked "In Stock". Richard's version returns the next record to blank.

I am concerned that this would mean someone could check out an item to the wrong customer. If someone is able to help I would be very appreciative.

Kindest regards
Rhonda
