Confirming Selection From A Listbox

Hi there

This is what I'm trying to acheive and I'm sure its possible but cant quite get my head around it to do it.

I have a form with a multi select list box from which our customers can select a number of items they would like added to their worklist for the day. They then click on a command button which then sends those items to a table from which our employees then generates a worklist.

However what I would like is that once the customer has entered their selections I would like them to be able to click another command button before submitting the work to the table which would then show them the selections they have made before the info is submitted to the table. They would then review what they've selected and make additions or subtractions as neccessary.

I'm not sure whether or not I have to create two tables the first of which would hold their initial selections and then the first button would then run a query based on that first table and then once they click the submit button it sends that info to another table from which the days worklist can be drawn.

Another question is what if once they've reviewed what they've selected and wish to remove something? If selections go to a temporary table and then they unslected an item will that remove it from the table or would it create a new record which is not what I want.

If you could help that would be most aprreciated. I know very little in the way of coding so any explicit instructions would be most welcomed

regards

Steve
