trouble with for loop and ASCII encryption; just about done

[Tomdon]

So I have all this code and just one more thing to figure out. I have to input text. Then text is output as written, in all lower, all upper and then in ASCII encryption where '~' is ' ' (space bar) and vice versa with 'O' being the same value. This encryption takes into acccount all characters on Keyboard. My problem is that this encryption takes the all uppercase iteration instead of original input. Here is code: try using a(should be =, instead it is ]). Thanks here is code.
