Access Updating an access table froma form that includes a listobox

[Glenda Morrison]

I'm trying to update a table that is based on a form that includes a list box. I am a little familiar with VBA code but can't figure out how to accomplish this. I have a customer table and a price table. The prices are based on the price item codes selected. I have reviewed lots of vba code examples but have not been able to implement them.
