dreamweaver dynamic list menu value equal to multiple

[danblack30]

I have a list box set to accept multiple. I have three names in it...Justin Jeff Dan. When I click on the dynamic button and select value equal to <%= (Recordset1.Fields.Item("Res_By").Value) %> , I get 1 name returned(highlighted) but not when I select multiple names. I assmue it's because the field on a multiple select would be Justin, Dan (for example) and that wouldn't match the list menu entries.
Any ideas??

Thanks,
Dan
