ASP / Incorrect syntax near '#' in Between SQL statement

Hello

ASP ---> I keep getting an error page message. The code doesn't seem to parse or the syntax is incorrect.  Do you know what may be wrong in "Between" statement.  It connects to a SQL Sever DB and I know it checks the tags first ... I don't thinks that I miss place one.  

Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near '#'.


  strSQL="Select * From SQLTbl "
   strSQL=strSQL & " Where [call date] between "
   strSQL=strSQL & "#" & varGetStartDate & "# and #" & varGetEndDate & "#"
     
   Response.Write "<HR>" & strSQL & "<HR>"
   
   rs.Open strSQL, conn, adOpenStatic

Thanks.
