Help in IF condition

Hi,

Can anyone help me for IF condition in attached sheet column I to L.

I want below condition in column I to L:

1. If I have received payment before 30 days then column (I to L) will be blank.
2. If have received partial payment then remaining amount will be show under the column (I to L) which days is fulfill. Ex-if I have received payment
in between 30 to 60 days then amount comes under Column “J”resp.
3. Amount only comes under column (I to L) when its fulfil it days. Ex- if payment not received till 40 days then it’s come under column “J” resp.


Thanks in advance.
