[tunait]

hum... has probado a scarle las comillas a <% =Session("MM_UserAuthorization") %> y a <% =InStr(1,MM_authorizedUsers,Session("MM_UserA uthorization"),1) %> ???

if ( <% =Session("MM_UserAuthorization") %> != ""
&& <% =InStr(1,MM_authorizedUsers,Session("MM_UserA uthorization"),1) %> != "0") {
window.open(jsStr);
}
else {
window.open("../../Servicios.htm");
}
