If you view source of the page, you will see the following error:
var address_0_48 = {
street: ' <font face="Arial" size=2>
<p>Microsoft VBScript runtime </font> <font face="Arial" size=2>error '800a005e'</font>
<p>
<font face="Arial" size=2>Invalid use of Null: 'CStr'</font>
<p>
<font face="Arial" size=2>/Corp/SM/google_javascript/wagmp_map_3.asp</font><font face="Arial" size=2>, line 147</font>
This means that one of the records in your database has a NULL value in the street column.
Make sure that all of the addresses in your database are complete and have a value for the street column
