Need To Determine If Records Are Already In Database

Problem: I can add 4 items to a SQL 7.0 database but I need to redirect the user if all 4 items exist in the same Record elsewhere in the Database.

Clearly I need some kind of statement like "if category1 = var1 AND category2 = var 2 AND..." but don't know where to put it.

Code:

strSQL = "SELECT * FROM tblUserQuarter"

Set objRS = Server.CreateObject("ADODB.Recordset")
objRS.Open strSQL, objConn,adOpenStatic , adLockOptimistic

'Insert choices from report.asp into tblUserQuarter
objRS.AddNew
objRS("cboFY") = Request.Form("cboFY")
objRS("Quarter") = Request.Form("Quarter")
objRS("ID") = Request.Form("ID")
objRS("Report") = Request.Form("Report")
objRS.Update

objRS.Close
Set objRS = Nothing
objConn.Close
set objConn = Nothing
