you're welcome
be prewarned - it will be messy - if you're entitled to more money, you'll get a top up of ftb, and a top up of ccb. BUT, because you get more ccb, you have then been overpaid CCR, so they have to create a debt for that, and take it out of your ccb top up.

so, if you're entitled to another 100 for ccb, it means you have 100 less in out of pocket costs, so you've been overpaid ccr by 50 (half of the ccb amount you got topped up) so you'll only get your ccb top up of 50

hope that makes sense!
