Need help with, if condition

[DamasGate]

Explanation:

I install a hack, "show user last 5 threads above his signature".

If user has more than post on the same thread, Show only one time his last 5 threads above his signature.

Like this:
<if condition=" THIS IS THE FIRST USER REPLY ON THE THREAD

show user last 5 threads above his signature

<if condition=" THIS IS THE The second, third, or fourth REPLY ON THE THREAD

DO NOT show user last 5 threads above his signature



I hope that is Clare
