When you get to the combat part . roll your attack .. use any modifiers .. and write the attack followed by the dmg including any modifiers
So if my BAB was +2 and my str was +3 and I had bless +1
A roll of say 14
I would write 20 (14+2+3+1) for my attack
If I wield a longsword (dmg 1d8 ) and roll a 6
I would write down my dmg as 9 (6 + 3) (Str Mod)
To post I would use the format atk|dmg
So I would write atk goblin; 20|9 (or something like this)
I hope this clears it up .. if not write down specifically what is still confusing and I will elaborate more
