I need to write a vb script that when the select box named LSP in an XSL page is set to JKW then focus must go to another select box named LMB and the user should not be able to leave the LMB box until something is entered or value is not null. I don't want the LMB box to even be available until the LSP box is set to JKW. It should either be disabled or invisible. Any help would be appreciated. Thank you.
