Noob new help on macros

Does any one know any good iniative script that add your iniative modifier 

Every character sheet/game system might have a different attribute name for initiative modifiers.  You should specify what game system you are playing and which sheet if there is more than one sheet available for that system.

Basically what Kraynic said, it helps to specify what system you're using.

However, for 5th edition I am fond of making a macro that says;

/em rolls a [[1d20+@{selected|initiative_bonus}&{tracker}]] for initiative!

and it works perfectly but it doesn't need to be that elaborate.

Ok how about 5e how about a spell that the damage goes up 1d6 per level how would u write that
