My image contains lines of code that should be generating the graph of an equation in a manipulate. The code is not generating the graph. When I press down on 'Evaluate' the graph appears for a few seconds, then it disappears. Do I need a semi colon someplace? Do I have too many semi colons? Thanks to all of you in advance.
Your Manipulate works fine on my system.

That is good to know. Before I composed this notebook, I got an error message. I tried to open a fresh notebook. Mathematica told me I needed to activate my copy of Mathematica (I am on 13.2). The error message went away after a while. But this notebook has never functioned properly. I am on Windows 11 Pro running 128 GB of RAM. Should I reinstall Mathematica? How do I reinstall Mathematica?
Please post code that can be copied, pasted, and evaluated, rather than an image. What are dtplt1b and dtplt1c?
dtplt1b
dtplt1c
O. K. I am adding the entire notebook
