CR7 and VB question - Very urgent

Hi friends, I am having some problem here.
My Project Details:

Front End: VB6
Back End: MS Access

Present status: Completed everything except the reporting
Data connection used in the project: ADO

Reporting Tool used: Crystal Report 7

My problem: I had completed everything except for reporting. So, for creating reports, I clicked
the Add Crystal Report 7 from Project menu.
Then selected the Standard option. Now I selected Data Objects. Then
I selected the ADO option. There, it is asking for the connection string.
What should I have to use???

Please help me..
It's very urgent. I had to submit the project within a few days.:(
