How can I get the What's This button to work on an Access Form

[pa2]

Hi All,

I am trying to use the What's This button on an Access Form to return ContextID help topics when you click the button and then click on a Control on the Form.

I have created the html .chm help file and it contains the necessary popup topics which have an ID number. However when I set the values on the Access Form to the .chm file name and the Controls to the appropriate popup topic id it does not work.

I have tried every conceivable method and variation and still it does not work.

Please can somebody provide me with a sample database that show's the What's This button actually working as this is the only way I am ever likely to see this working.

Thanks in advance for any help.
