Register post fee with ozzy post module

[kennyoz]

Hi,

Has anyone figure out how to increment the fee for the register post option in the ozzy post module?

The default fee for register post is $2.60. This is for purchase price of up to $100. For purchase upto $200, the fee is $3.75($2.60 + $1.15).
For every $100 extra, the fee increases by $1.15.
For purchases of upto $300, the fee is $4.90 and so on...

I tried using 100:2.60,200:3.75, 300:4.90. However this does not work.

Is it possible to have conditions in the register fee box?

Thank you.
