Manipulate does not work after resetting?

Hey, I'm currently doing mathematica for school and I am trying to complete this lab (as attached). I was able to perform the manipulations function in the "answers" section but after rebooting my laptop for an unrelated issue, the manipulate blue line doesn't appear anymore; so I'm not sure what went wrong. Answer Section, Question 4&

Currently using Mathematica on Opera and issue appears even when the file opened in safari.

I was wondering if/when wolfram prompts

"Evaluate initialization cells? Do you want to automatically evaluate all the initialization cells in this notebook? Cancel/No/Yes

has an impact on this?

So much for "Have you tried turning it off and on again?"

You need to evaluate initialization cells, along with the cell that contains

model1[n0_,k_][t_]:= n0 Exp[k t]; (* modify the definition to reflect your model choice *)

directly above the Manipulate object.

If you want that manipulate output to immediately be usable, it might be best to set the cell that contains the definition of model1 as an initialization cell as well.

I assume you just need to evaluate all the cells again. Definitions in the environment typically go away when you shut down Mathematica. Evaluating the initialization cells might work if the necessary definitions happen to be in the initialization cells.
