fill' between two lines? Pine-script

Question

How can I fill up an area with yellow between fib 50 and fib 61.8 lines (probably around line 111 in the script @ 'fibolines'), e.g. using fill?

I have tried playing around with:

hh1 = hline(y1, color = color.gray, linestyle = hline.style_solid, linewidth=1)                                                  
hh2 = hline(y2, color = color.gray, linestyle = hline.style_solid, linewidth=1) 
fill(hh1,hh2,color=color.yellow, title="Background")

but it gives errors because of y1 and y2. Source code:
