Trouble with JS

[Imahigo]

So, I'm trying to make this game where you can change the color of the character. Unfortunately, the JS script call code that I wrote gives me an error and I cannot figure out why this does not work.

var faceName = 'M_Hero_Faces_' + $gameVariables.value(19); \\variable 19 is the group name for the file.
var walkName = 'M_Walk_' + $gameVariables.value(19);
var battleName = 'M_'+$gameVariables.value(15)+'_'+$gameVariables.value(17)+'_'+gameVariables.value(16)+'_'+$gameVariables.value(18);

\\variable 15 is the hair color, 17, the clothing color, 16 the eye color, and 18, the skin color

$gameActors.actor(1).setCharacterImage(faceName, $gameVariables.value(14));
$gameActors.actor(1).setFaceImage(walkName, $gameVariables.value(14));
$gameActors.actor(1).setBattlerImage(battleName);
$gamePlayer.refresh();

I have been at this for over a month now and I still cannot figure this out no matter how much I google. It's really frustrating. There's an alternate method by using conditional branches, but there is roughly 5,000 different color combinations for the player character and I don't want to keep using conditional branches for every variation. I thought by using variables and loading the filename that I set with the variable number would work. Is there an oversight that I'm missing, or do I have to use a plugin for this?

Two things to say.
1. Comments are not \\, but //
2. It would be nice if you'd share the console output to say what error it exactly is. It's nice that it gives you an error, but there are myriads of errors one can receive.

Thanks for the comment lines, but those are actually not in the code. I just put them there for your convenience. But this pops up.

Actually problem solved! I forgot the $ on one of the gameVariables.value()! It's all good now!
