Returned Expense for Available balance is less than requested amount

[Nsud]

I have a returned expense for "Available balance is less than requested amount". I don't understand what that means. I haven't changed any amount. Please help. Thanks!

@Nsud this issue appears to be cleared up, correct? I don't see any returned reports in your profile.

Hi Kevin! Not yet. Sorry, I forgot to mention I'm asking on behave of a coworker. Does he have to be registered here for you to be able to see his expense? Thanks!
