Roll Number of Dice Equal to Characteristic

I tried to look in the wiki and did not see it (although I did learn some other cool stuff).

How do i set a macro to roll a number of dice equal to the targets atribute? I know what I tried is wrong because it does not work, but I also know there are dozens of systems that do something simular so...

Example Joe has a Stamina 8 so I want him to roll 8d10
/roll @Joe|Stamina - D6

Try /roll {@Joe|Stamina}d10, possibly with regular parentheses.

Here you go:
/r @{Joe|Stamina}d6

Awesome it worked. I imagine I need to pay closer attention to syntax. Looks like I was forgetting the {} in my formula.

PS: I did not know I could just use /r instead of /roll Thanks Gauss.
