Database Error when trying to save origination rate

Hello,
I've saved origination rates in the past and have 100s of them setup infact. However, I tried to add a new rate this evening and nothing happened.
I discovered that the AJAX call to origination_rate_save/ was returning an E500 and the error is duplicated below.

`A Database Error Occurred

Error Number: 1064

I have done an update 5 mins ago and it did not help.
