	Line with $value is unnecessary - when you select more than one items then it returns array in array. I've removed this line from the source code - now it should works fine.

-Has anybody successfully implemented a multiple item select list parameter type ???
+I tried this code in my application and it almost worked but not exactly.
-EG <select name="params[userid][]" id="paramsuserid"  class="inputbox" multiple="multiple"> is generated by the example given on this Forum..
+When I selected more than one item, the parameter was saved in the database as:  p1|p2 rather than p1,p2 as would be the normal case of html.
-This "select" syntax  does not appear to have any chance of working as sideline tests do not work.
+If I then go to the database and change it manually to p1,p2; then it displayed correctly in the administrator..
-If anyone has succeeded, please reply with at least a yes and some hints.   thanks.
