Hello, I am dealing with two fields; "Error Category" and "Error ID". Each cooresponding error ID has a cooresponding error category (They are matched in up a sepearate table). In my errors table, I have created a lookup field in the "Error Category", which allows a used to select the error category from a drop down list. I would than like for the appropriate error ID to populate into the "Error ID" field based on the error category that is selected. How is this accomplished? Thank you
