Actually, there's no error message.
It just only lets userid '1' deposit money.
I added the user 'bank' in the admin panel and gave it 10000000, and it worked, it had 10000000.
I went to the bank logged in as 'Bank', and deposited all 10000000, and it said:
Or something of the like. The 'Deposit' bit was empty, not even '0'.
Here is a screenshot of the phpmyadmin 'items_user' table:

PS: It seems to me that when you add users in the admin panel, it's not adding those fields correctly.
