This is my first time here and I would like to say hello to everybody.

TRO.
I hope you can help me.
I am not a coder. I picked up an indicator (yours) from the TSD and I did some modifications in order to show the range of the open and the Buy and Sell Zone and the triggers. But due to I am begining with your vision of the trading I would like to add a shadow (rectangles) to all the Buy Zones. Then, I made some modifications to other indicator but I have some errors. Could you please (or somebody) help me to fix it indicator?
I attach two picts and the indicators.
Thanks in advance.
