Revit Dynamo Python Error

Revit
1

Howdy,
I have been trying to write something to create sheets and place views on them. In my search for pieces I came across a youtube video that shared a script with custom nodes in them. I have recreated the python portions of it but I am getting some error messages that I do not understand. See below screen grabs. In googling these, I came across some Iron Python vs Python issues. I have followed all the steps in the GitHub blog post to remedy those. I am thinking maybe there is another issue in here somewhere. This is my first attempt with Python so I am not that great at reading or understanding it yet. Sorry if it is obvious. Both of these yellow nodes have the same errors. I can only post one image so I linked to the images below.

The lib you might want to load is clr.AddReference(ā€˜RevitAPIā€™)
not
clr.AddReference(ā€˜Revit APIā€™)

Whelp, that helped it to run past line 4 but now its giving me a different error message on each of them. I have pasted the two node text bodies below if that helps. I am not sure what the errors mean. Error message images are here:

The error implies that you arenā€™t capitalizing your booleans (True, False), but your code doesnā€™t show that, so Iā€™m not entirely sure of whatā€™s going on.

You use ā€œNumberā€ in the for, but [number] in the code. Verify all your capitalization for variables.

I had two other capitalization errors in the python. Thanks so much everyone! works great now!
