cmdButton to open form to enter related data

[Ratte]

What I have is a form with project details and a cmdButton.
I also have another form with burner types.

What I am trying to do is typing in my project details and click on the cmdButton to open the burner types form.
Then I type my burner details into that form and close it.

The problem I got is that I got the form to open up as a popup but it won't relate the data I enter to the project.

Thanks for your help.

try form wizard and in the sub form use linked pop up form that will automatically do the coding for you

I did that but it won't relate the data to the form with the button on it.
I can enter a record but it dosn't do the relationship between the two tables.

Does some relation exist between two tables
