Create Box or vertical line offsetting session time which splits using Fibonacci ratio - time

Question

I have completed the main objective of dividing the day into "cycles". Now, I am having trouble with creating a "sub cycle" within each zone that is defined. I basically am trying to take a cycle (sesionTime1) and split that at 0.38 and 0.62 be it with a vertical line that only goes from the overall session high/low, or just create another box where the start of the box is at the 0.38 and the end of the box is at 0.62. I have tried defining sessionTime1 * 0.38, but thats not working for me. And, using bar_indez(X) only focuses on the bar movement which will change as the timeframe on chart is changed.

I am attempting this addition at the very bottom unde3r SUB AMD SECTION. Any help/guidance is greatly appreciated.
