Correcting a transaction

Today you have been given a script which is not correct. It was written by a colleague of yours who didn't know how to finish it. Your colleague tried to transfer $100 from account 1 to account 5, and register those movements into the transactions table.

You immediately realize there are several errors. SQL Server doesn't recognize the transaction statements it uses.

Can you correct the script?
