quick question on macro order of operations.

I am familiar with PEDMAS, but when I try to use the below macro it does not output correctly. !power --name|Damage Calculator --Total:|[[floor(?{damage|0}-?{Damage Reduction|0}*?{Damage Type})]] so the above has the issue where it multiplies the damage reduction by what ever you put in the damage type. I understand why it's doing that. and presents it on a power card. I tried this: !power --name|Damage Calculator --Total:|[[floor((?{damage|0}-?{Damage Reduction|0})*(?{Damage Type}))]] and it outputs the number correctly But Does not output a powercard. why would the small change between the two cause that?

I have no idea, but check the javascript console when you execute it.  Using a Roll Query has a bug that causes any errors from an inline roll to be printed to the error console, rather than the chat.

javascript console.... that's the API output console correct? if it is, no error appears there.

No, the browser Javascript Console.  Usually accessed via the Developer Tools.  In Chrome, you can find it under View->Developer->Javascript Console.

hmm, I think I'm looking at the correct thing, but I am not seeing any errors.

Probably you need to add a default case: !power --name|Damage Calculator --Total:|[[floor((?{damage|0}-?{Damage Reduction|0})*(?{Damage Type |0 }))]]

ahh I see. Thanks alot The Aaron! That works perfectly!

Cheers!  Happy Rolling!
