What i use is: 1. UpdateForm (DTML-Method) 2. List_available_items (ZSQL-Method) "select ap_id,ap_docname from AliasPages where proj_id=<dtml-sqlvar proj_id type=int>" 3. List_selected_items (ZSQL-Method) "select ap_selection from Projects where proj_id=<dtml-sqlvar proj_id type=int>" Problem: I want that the Checkboxes are "CHECKED" if "available_items" == "selected_items" I am not sure if my dtml is wrong or the sql-method: ! See the TIP at the end of this mail ! **************************** Here the: "UpdateForm" **************************** <dtml-call "REQUEST.set('selectedITEMS',[])"> <dtml-in List_SelectedALIASPAGES> <dtml-call "selectedITEMS.append(proj_id)"> </dtml-in> <dtml-in List_available_items> <input type=checkbox name=ap_selection:list value="<dtml-var sequence-item>" <dtml-call expr="REQUEST.set(selectedAP,_['sequence-item'])"> <dtml-in List_selected_items> <dtml-if expr="_['sequence-item'] == selectedITEMS"> checked </dtml-if>> </dtml-in> <dtml-var sequence-item><br> </dtml-in> </TD> </TR><dtml-comment>colname:ap_selection,table:Projects</dtml-comment> **************************** Here a tip i found: "How to construct such a query? If you know, that your values do not contain quotes (i.e. '), then you can use "_.string.join" like this: select ... where col in ( <dtml-var "_.string.join(multiple_selection,',')"> )" I recognized that a lot of USERS have these problems with "Multiple Selections". So if you will help to find a good way to manage this i will post a "How-To" in Zope and i wanted to create an ADD-ON for the great product "ZNolk". THANX you all for your time. REGARDS Richard
