You can try: <dtml-in List_available_items> <input type=checkbox name=ap_selection:list value="<dtml-var "_['sequence-item']">" <dtml-if expr="_['sequence-item'] in List_selected_items"> checked (<dtml-var "_['sequence-item']">) </dtml-if>

<dtml-var sequence-item><br> </dtml-in> You have a list and you must ask for membership (with 'in'), also you can save one <dtml-in>. Best regards Arno

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>

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
