Been awhile - cant seem to add [[Ability_mod]] inline to my macro

normally when I create attacks & Spellcasting, In the description box I tend to add any other info and sometimes additional inline rolls.

So let's pretend I have a homebrew ability, I create the attack, put in the relevant info on the attack but there are few other things I cant add, so I will put it in the description. example

Natural healing
1d12+2
 
description - players within 10 ft of you also receive temp. HP equal to your constitution modifer
[[@(constitution_mod)]]

and when I test the attack - it would show the con mod #

I also remember never ever using the selected|constitution_mod format.

is this no longer possible?

So it may just be how you wrote it here, but the correct way is to write @{constitution_mod} rather than @(constitution_mod) . 

Which character sheet are you using? Without that information we cannot determine if the attribute is named correctly.

5e OGL

edit - removed.

So [[@{constitution_mod}]] should work. If it doesn't please let me know.

Yep, as Gauss says, it looks like you're using parentheses instead of curly braces around the attribute.

I just quickly mocked this up in the description field and it worked correctly:

Players within 10 ft of you also receive [[@{constitution_mod}]] temporary hit points. 

I could have sworn I tried those brackets too lol. Thanks.

now how do I get athletics_roll to show up?

Trying to set an attack macro for grappling. I am a battlerager, so when I do grapple, they take 3 piercing damage. Trying to include in the description my contested athletics_roll they need to beat. 

the [[@{athletics_roll}]] doesnt work

@{athletics_roll} is a templated roll, so you cannot use that as you are already inside another template (the attack's description is inside the attack template).

You will have to create the roll from scratch. Example: [[1d20 +@{athletics_bonus}]]
