Delete multiple records

Hello all,

Please be patient with me as my experience with databases is very limited,and I am hoping there is a simple solution.

In my application I have a form named "Controllers" in this form there are three fields "Serial Number", "Max Temp", and "Hours"

I am trying to create a lookup function for the form named "Controllers" I want the function to lookup the "Serial Numbers" of all of the "Controllers" in the form and display them as selectable check boxes. (This Part I know how to do)

I then need to be able to select individual checkboxes based on the displayed serial number, and when the user selects "Submit" the selected entries should be deleted from the database, along with the "Hours' and "Max Temp" data as well.

I have read the help entry on the deluge script but i do not understanding how to write the expressions.

Thank you in advance for your time,
Jason
