Returning A Recordset For A Form

I am setting up a form using a couple combo boxes. I want to populate a text box or 2 from the item record selected from one of the comboBox. Below is the code I am using.I have commented out where I am trying to transfer the value to the form, and try focusing on the query. When I run this code I get a type mismatch.
