Oh I am kind of stuck in the middle trying to figure out the logic right now. it obviously doesn't work.

You never really asked us for anything. How would you like us to help?

It doesn't work I need help fixing it so it works properly lol.

Okay. Great. That's still not answering my question as to how you'd like us to help. You never tell us what's broken or what you'd like us to do.

Would you mind please reading this?

But what does "it doesn't work" mean? That's like telling the doctor you are ill, and asking him to make you well again.

Before he can help, he needs to know what are the symptoms.

The first loop will check for the.! To break the loop but the second input prompt doesn't check for the explanation point. And when it prints out the input it's supposed to capitalize the letters but it makes them ascii symbols instead. And it also modifies the numbers in this way too. So a vast majority of it is broken..
