Form attached to a query

[gdanalakshmi]

I have a form whose record source is a query. The form has a list of textbox and listbox controls. When I create a row in the listbox, I add a empty record in 2 tables. One is the table attached to the form itself and other TableB.

When I type the data in all the textbox controls, I need to update TableB. WHere should I put the Update query?? I am looking in the forms afterupdate event??
Am I correct??
