OK Last calculation help needed

### Post

i am building a table for a form I have, and I am racking my brain on this one

lets say i have a Principal amount and an Interest Amount  (For example we'll say \$5000 Principal and \$100 Interest)  I received a payment of \$300.   My chart has to show how the payment splits.  In my case all payments go to interest first so I need to have two fields outputted here...one will be for \$200 (towards the principal) the other will be for \$100 (towards principal).  Its easy to do when the Interest is higher then the payment, but its not simple when the payment needs to be shown as split between the two

example

5000princ  100int

200          100        =300

-----------------------------------

4800        0

and

5000princ  450

0               300       =300

-----------------------------------

5000         150
