A combobox can't be used for multiple selections like a listbox.
You would need code to "remember" the selections and also a way to deselect erroneous selections... :-(

Personally I would offer two subforms, one for each combo.
These subforms are bound to a table1 with the "Category" and a YesNo field and the table2 would hold the products and also have a YesNo field.
Now the user can click the YesNo fields for selection and you can show a third subform at the bottom based on the searchpage query/table. This table can be JOINed with the table1 and table2 and when you add for the YesNo fields the criteria "True" (without quotes!), then the user will directly see the effect of the selections in the upper two subforms.

Idea ?

A combobox can't be used for multiple selections like a listbox.

Actually, this statement is only true thru version 2003! Access 2007 added the multi-select capability to Comboboxes.
