I am trying to submit an expenses claim.

I have attached my receipts etc.

The claim is for £1063.95 and I can see this needs to go to 3 different approvers however when I try to submit, the response I am getting is THIS REPORT CANNOT BE SENT TO THE NEXT APPROVER BECAUSE THE SELECTED APPROVER IS NO LONG AUTHROIZED 

TO APPROVE REPORTS.  SELECT ANOTHER APPROVER OR CONTACT YOUR EXPENSE ADMINISTRATOR FOR ASSISTANCE.

I dont know how to contact my expense administrator.

I really need some help
