Random variables

Hi, I know that: $game_variables[5] = rand(6) would make a game variable a random number,

But... how would I do this:

@damage = rand(@damg- @randm)

Where @randm is a variable with a value, and @damg is a variable with a value.
 
You're not very clear.
Code:
@damage = rand($game_variables[5] - $game_variables[6])
Is that what you want?

Or do you mean making @randm and @damg into variables?
If so:
@randm = 1000
@damg = rand(@randm/2)

As examples. Try to be clearer.
 

Thank you for viewing
