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.
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
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?
