Geerate Data Report

I have a VB program that access' a Access DB. I have one form set up where the user selects which fields he wants the data from to be placed on the data report.

2 questions:

1) Do I need to design the report layout, or does VB automatically place the controls on the form? Currently I only have a blank data report created.

2) Below is the code I have on my click command of my command button to generate the report:

Private Sub
Command1_Click()

DataEnvironment1.Soldiers cboSource1.List(cboSource1.ListIndex)
rptSelect.Show

End Sub

What am I missing here? Whenever I click it it gets an error :

Compile Error:

Wrong number of arguments or invalid property assignment.

Your help is appreciated.

Thanks

Robert
