need Help with multiple sql criteria

[Rand]

combo 86 is text and i keep getting an error see attached image
the numbers are date serial numbers. it works if i dont use the combo86 clause
the syntax is as follows:
strSQL = "SELECT Qry_CalDataBS.dte,Qry_CalDataBS.bs "
strSQL = strSQL & "FROM Qry_CalDataBS "
strSQL = strSQL & "WHERE Qry_CalDataBS.bs = '" & Me.[Combo86] & "' "
strSQL = strSQL & "WHERE (Qry_CalDataBS.dte) Between " & lngFirstOfMonth & " And " & lngLastOfMonth & " ORDER BY "
strSQL = strSQL & "Qry_CalDataBS.dte;"

it is from a populated calendar i got somewhere and trying to modifyy it to show just certain records based on the combo 86 dropdown.
tnx

You can only have one WHERE clause, but it can have multiple criteria separated by AND or OR.
