Voucher Approval Amount

I am needing to change our Voucher Approval Amount in PeopleSoft.  I have tried changing it in the Main Menu > Enterprise Components > Approvals > Approvals > Approval Process Setup area under the "Criteria" link, but when testing it does not force an approval when the voucher is over the updated dollar amount.

Is there another place this approval amount needs to change?

Thanks,

Jessica
