You could start with a blank form.
Now what do you need to do???
This is what you said
Code:
You said you wanted
to hit a button
which will open up a query and
show the records related to that developer
This what you will need, based on what you said
So you need a button with a Click event
which will open a query
that will Select records related to some developer???
Which developer??? Where will that info come from??? A dropbox... which dropbox?
What will be in the drop box?? Where will that data come from??
I think that's a bit of help to get you started.
Update/edit: I see Alan posted while I was typing.
