HOW TO MACRO? help please

Hello so im not great with making these macro things what I  am trying to do is make it so that if I roll a nat 20 it does something special like something pops up and says critical hit or something like that this is what i have so far &{template:default} {{name=Initiative}}{{Results=[[1d20+4]]}}

Not as dramatic as a pop up, but you can add a critical success threshold "cs>X" to your macro which will highlight your inline roll in green if your roll is greater than or equal to the threshold.  I placed your modifier before the roll since you want the critical success based on the roll not the modified total. &{template:default} {{name=Initiative}}{{Results=[[ 4+1d20cs>20 ]] }}

thanks, ill give this a try appreciate it I'm trying to learn the macro lingo it's too much like coding lol and I'm not the greatest at that
