I'm trying to pass 3 parameters to a stored procedure but can't figure out how to do it. Here's the gist of the parameters I need to pass. Bear in mind I'm not sure about the syntax.

FillList.CommandText = "prGetOutCustRMA
(lstCompany.list(lstcompany.listindex) ,txtCustDate1.text,txtCustDate2.text)"

I need to pass the values in the list box, and two text boxes. I continue to get errors. Any hints?
