Expression Control for Font Size and Repeat

Hello,

I have attached a picture of the layout I'm working with. What I have currently is the following expression on the word QUICK to control font size:

text.sourceText.style.setFontSize(effect("Size")("Slider"))

For the other QUICK(STROKE) I have the following expression to repeat in the Y-POS:

var y = thisComp.layer ("QUICK 2").effect("Copies")("Slider");

(repeat(1) + "\n").repeat(y)

What I"m trying to do is connect QUICK font size and source text to QUICK(STROKE) so that I can change the word and size to anything and the repeating version will match. I am having trouble understanding how to do so. Please let me know if there are any other variables needed. Thanks!
