What does your roll button value look like?

<button class="myrol" style="width: 100%;" type="roll" name="roll_attack" title="Attack & Damage roll" value="@{whispertype} &{template:pc} {{name=@{atkname}}} {{charname=@{character_name}}} {{roll=[[(@{atk_DP_sum}+@{atk_reduce})d10>8!@{atk_again}]]}}{{notes=@{atk_notes}}}{{atk_bonus_used=@{atk_bonus_used}}}{{atk_bonus_used_amount=@{atk_bonus_used_amount}}}">

Ok, so, in order to use the #rollgreater helper functions (or any of the roll... helpers), there has to be a roll in that field. Change the field in the roll to: {{atk_bonus_used=[[@{atk_bonus_usedd1]]}}}

That's work. Thankyou very much!
