Syntax error in WHERE clause

i seem to be getting this error message on my intranet page
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC Microsoft Access Driver] Syntax error in WHERE clause.
/TelHMY.asp, line 24

The WHERE clause in question seems to be
<%
var HMYTel = Server.CreateObject("ADODB.Recordset");
HMYTel.ActiveConnection = MM_UseTelephone_STRING;
HMYTel.Source = "SELECT * FROM UseTelNumbers WHERE Group = '"+ HMYTel__MMColParam.replace(/'/g, "''") + "'";
HMYTel.CursorType = 0;
HMYTel.CursorLocation = 2;
HMYTel.LockType = 1;
HMYTel.Open();
var HMYTel_numRows = 0;
%>

HMYTel.Open(); is line 24.
The page is javascript .asp with a MS access database.
Any ideas
