Access Form. New code for new record interfering with OK and Cancel button

Hi

I have introduced a "New Supplier" button on my Access form, which has an "OK" and "Cancel" button designed to save changes
if the user clicks "OK". The introduction of the "New Supplier" button has caused errors. If I click this button, fill in y information
and click OK things seem to work fine. I get the expected "Changes saved" message. If I then go and click the "New Supplier" button
again I get the error shown in the image further down
