Hi @EmmePGN - can you try this code instead:   <script> var v_Knowledge_New = "[@field:Address]" ; var o_Knowledge_New= document.getElementById("EditRecordAddress") ; o_Knowledge_New.multiple = true ; document.addEventListener('DataPageReady', function (event) { if ( v_Knowledge_New.indexOf(",") > 0 ) { for (var i=0 ; i < o_Knowledge_New.options.length; i++ ) { if(o_Knowledge_New[i].value == v_Knowledge_New) { o_Knowledge_New.remove(i); break ; } }
