Dropdown Issue

Hi

Last Name



City

  Office-1
  Office-2


Schools:

 



  Office-A
Office-B
 


  Office-Y
Office-Z

What is happening , currently it display both selects , which i don't want . I want when page loads it should display in City Dropdown Office-1 & corresponding dropdown list with Office-1 i.e Office-A,Office-B.

When city changes say Office-2 then location should also change i.e to Office-Y,Office-Z.

Above code is working fine in Google Chrome though , but in I.E it is giving problem.


Thanks
