I created a form and tested it by creating new data. It was working fine. See TestDB enclosed
When i appended the data from Excel one field does not capture the data from the table, all others do. I tried to delete and recreate the field in the form. No result. The field name is DebtorCode
Also the new records are created with a very different ID which is 5 digits. I experience this in my other forms also from where I have copied these tables and Form
Look forward to some helpTest18May.zip
