[Ven]

Hi everyone! i'm using Yanfly's skill cost script

and I've been getting a weird error everytime i enter the skill screen in battle (containing the skill with the special skill cost)

This is my setup for the skill:

Spoiler

<custom cost: 3x>
<custom cost colour: 0>
<custom cost size: 16>
<custom cost icon: 192>

<custom cost requirement>
$game_party.item_number($data_items[1])
>= 3
</custom cost requirment>
<custom cost perform>
$game_party.lose_item(($data_items[1]),3)
</custom cost perform>

you had a typo:


</custom cost requirment>


should be


</custom cost requirement>
