I have been trying to insert a new opportunity using premium sync. It inserts everything except the employees.
I have tried the following variations with no success. The last try I manually edited and copied the code from the database and it still does not work.
$url .= '&f_employees=1';
$url .= '&f_employees=1,2';
$url .= '&f_employees[]=1';
$url .= '&f_employees=__1__2__';
Any help on this matter would be greatly appreciated.
