Inputting An Undetermined Variable

How would I input a specific variable into an equation that isn't tied to anything else? This is for a 5e campaign using the OGL Sheet. Ex:  [[ 2d8-x]]   and I have to manually input values for x

You would use a query

[[2d8 - ?{What is X} ]]

The Aaron said: [[2d8 - ?{What is X} ]] Here's my macro for a pretty believable equation so far. [[(((30*@{target|Target1|strength_base})-(@{target|Target2|weight}*2.5))/(27-@{target|Target1|strength_base}))-@{target|Target1|strength_base}]] It works so long as there are two tokens, target 1 has a "strength_base"(for DnD, it's the Strength Score) attribute, and target 2 has a "weight" attribute, but I want to eliminate the need for a token-tied "weight" so it can be more versatile with what my barbarian can throw. When I tried to add "What is X?" , I didn't get a proper output anymore.

So, something like: [[(((30*?{base})-(@{target|Target2|weight}*2.5))/(27-(?{base})))-(?{base})]] I'm not quite following what you're trying to do, so that's kind of a stab in the dark.  It should prompt you for a number, then use that number in place of where strength_base was.  (Note the ( ) in cases where you might get a double operator for negative numbers.)

I think its the weight variable that he wants to replace with a query. Thats a fairly complicated formula for determining how far you can throw something. Is that really how you do it in 5e?

Ah, thanks G G.   [[(((30*@{target|Target1|strength_base})-(?{weight}*2.5))/(27-@{target|Target1|strength_base}))-@{target|Target1|strength_base}]] I don't believe there's a formula for how far you can throw something in 5e.

This worked, thank you. There isn't a formula in 5e per se, but I tested this equation out on Desmos Graphing Calculator with a bunch of different Strengths and weights and it gave believable results.

Is that really how you do it in 5e? No, it's usually up to DM discretion how far an object can be thrown unless otherwise specified(Like a handaxe has a range of 20/60)
