Mervyn, Thanks for the reply. Seeding dates to the report form indeed is OK, opens and should work. However I am getting : Class does not exist repFormForm :: pushbutton4_onclick. This happens on any other pushbutton where the report is simple with no params to pass. I believe that the onclick events are Ok in themselves as per your suggestion using "Form.oPreview.open()" It appears that the onOpen event is causing this problem. If I remove it  together with 'onOpen = class :: FORM_ONOPEN' and just use  " do...with preview.wfm" the report renders. ( Albeit ignoring " file does not exist" for smallfonts and file path for messanger and accompaning errors.) I am at a loss to find a solution  to this having read preview usage etc. Trevor.
