Attack Macro in OGL

I am new in roll20 and i want to use this macro, but I really don't know what i should replace and for what i should replace: @{CHARACTERNAME|wtype}&{template:atk} {{mod=}} {{rname=)}} {{rnamec=CRIT}} {{r1=}} @{CHARACTERNAME|rtype}cs>20 + BONUSES]]]}} {{range=}} {{desc=}} @{CHARACTERNAME|wtype}&{template:atkdmg} {{mod=}} {{rname=}} {{r1=}} @{CHARACTERNAME|rtype}cs>20 + BONUSES]]]}} {{attack=1}} {{range=}} {{damage=1}} {{dmg1flag=1}} {{dmg1=}} {{dmg1type=}} {{dmg2=}}} {{dmg2type=}} {{crit1=}} {{crit2=}} 0 {{desc=}}

If you want to see these macros in action, click on the Attack within the character sheet and then click the up arrow while focused on the chat window.

I was wanting to make this macro work to don't open the sheet all the time
