As far as notetags go I'm not really sure how that works but I'll google that to see what it is.
Googling for notetags won't help - you need to follow the rules set by the ABS you're using, googling for notetags can get you the thousand different ways to place the notetags of thousand other scripts, which will simply be wrong because they are for different scripts.
You need to read the instructions of Falcoa's Liquid ABS, NOT any other notetag descriptions.
However, if you don't even know what notetags are in general, then you need to stop using that ABS script and start doing some tutorials on RM.
Setting up an ABS script is among the most difficult things to do other than programming your own scripts, and I do not recommend that for any new user until you got some experience with the program.
