Those impossible data Reports!

Ok, here it is. I am working with VB6, within the data environment, and I am trying to create a report by passing it multiple parameters. I am succesfull in passing one parameter from a textbox to the report...(as long as it is not a string...another problem) and generating the report. But I can not pass in multiple parameters! If some one has the code or can explain how to do it I would be quite happy.

This is the code on the form for my sucessful report which passes one parameter:


Private Sub cmd_custnum_Click()

If IsNumeric(txt_custnum.Text) = True Then

DataEnvironment1.Custnum CInt(txt_custnum.Text)'passes what is in the txt to the paramter in my select statement

DataReport1.Show

Else

MsgBox "Please enter a valid Customer ID"

End If


And here is the code for my unsucessful attempt:


If IsDate(txt_invoicedate.Text) = True Then

If txt_vestype.Text "" Then

DataEnvironment1.Invoiced_date (txt_invoicedate.Text) & (txt_vestype.Text)

Invoiced_rpt.Show

Else

MsgBox "Please enter a valid invoice type"

End If

Else

MsgBox "Please enter a valid date"


End Sub


What about the value tab...I don't use it...should I ?

Lets face it I am lost!
