This could be because of the way you're setting up your sql string. Try placing single quotes around your prnno variable.

You may want to look at using a sql parameter for this variable. Setting up the query string as you have makes your application less secure.

I believe that the primary problem is that I don't see you connecting to the database with an sql connection. In MS Access you are in the database so that you don't need to connect. Here is an example that may help:

Hi, I hope somebody could help me with this problem. I would like to make a form to add and delete records from my ms access database. I've found most of the codes from the internet and adjusted some part of it. Anyhow, inserting records to the database seems to work fine, but deleting the records is not working as I want to and I just can't see what's causing the problem.
