Why does this work as a global modifier and not in a macro

I am trying to write a spell macro for firebolt.  It should produce a message in chat with damage rolled.  The roll should be the level appropriate number of dice. &{template:default}{{name=Firebolt}} {{Firebolt Deals=[[ ceil((@{selected|base_level})/4) ]]d10}} This is converted from: [[ceil((@{base_level})/2) ]]d6 used as a global damage modifier for sneak attack.

If you're talking about the Roll20 5e sheet, the global fields are automatically wrapped in an inline roll when the macro is constructed. You'll need to do that manually since you're building the macro yourself: [[ [[ceil((@{base_level})/2) ]]d6 ]] Just checking, are you using homebrew for the spell mechanics? Because level/4 is not the correct cantrip progression for normal rules.

Firebolt increase in die at 5, 11, and 17.  if you use ceil then /4 will increase the die properly.  So you are saying that it should work if I incase the line in {}

Double brackets: [[ ... ]] So you would turn this line: {{Firebolt Deals=[[ ceil((@{selected|base_level})/4) ]]d10}} ...into... {{Firebolt Deals=[[ [[ ceil((@{selected|base_level})/4) ]]d10]]}}

Interesting.&nbsp; I will try that. any suggestions here? <a href="https://app.roll20.net/forum/post/10583860/creating-a-spellbook-or-action-list-macro" rel="nofollow">https://app.roll20.net/forum/post/10583860/creating-a-spellbook-or-action-list-macro</a>
