Mark,
It sounds as though SET HELP is not set to your help file. You do not need to set individual controls unless you want them to display their own topic. If a control does not have a HelpContextID VFP will send the HCID of the form to the help engine.
>Well, I tried setting the form's HelpContextId to 16. When that didn't work, I did a select all in design mode and set everyone's HelpContextId to 16. When that didn't work I tried setting the WhatsThisHelpId to 16 as well.

>For some reason, the form is passing the context ID 1879048194 to the help engine instead of 16 (even though the form's help context id is 16). I'm stumped.
