Trouble with Modifiers

I'm trying to make a custom sheet and, while it isn't pretty, it works. The only thing that I'm truly struggling with is the ability modifiers. I can't seem to get the formula to convert to HTML correctly. The modifier is supposed to be the score subtract ten then divided by two but I can only get it to work as the score divided by two. I would greatly appreciate the help. Thank you so much in advance ^-^

Can you give an example that you've tried? There are several ways to do this, and i need to see what you are trying to know the proper advice to give.

<input type="number" name="attr_StrMod" value="@{str_score}-10/2" disabled="true" /> Is what I'm using and it works for the divided by 2 but not the subtracting.

Arty said: <input type="number" name="attr_StrMod" value="@{str_score}-10/2" disabled="true" /> Is what I'm using and it works for the divided by 2 but not the subtracting. try this: value="floor((@{str_score}-10)/2)" or value="floor(@{str_score}/2)-5" Both are equivalent.

Thank you both so so much! ^-^
