Subject Re: Preview.wfm and report printing From trevor <bob@bob.com> Date Mon, 30 Oct 2023 13:15:01 -0400 Newsgroups dbase.getting-started Mervyn , Both of your assumption are correct and  parameters added, clicking on report only works. I should have typed Pushbutton4_onclick1 in my message which is what I have on  my form correctly. Using newest preview.wfm but copied to my forms working directory so set procedure to Preview.wfm ---not useing set procedure to :duflp:preview.wfm Preview  seems to be available as I can open preview if no onOpen event.Also that is how I have used previous versions. I have used all your suggested coding. I have checked several times for typos and can find none, those in my messages are down to lazyness :) Also as I have said I tried the onOpen event and pushbutton Onclick form.oPreview.open() with another simple no parameters report and get same error. Perplexed but grateful for your help. Trevor
