it does not allow me to select buttons if something is entered in textbox-Collection of common programming errors

Open the browser console. When you click a button, you’ll see the following error:

Uncaught ReferenceError: currenttotal is not defined

It’s thrown by this line of code:

console.log(currenttotal);

There’s another problem which appears to be preventing currenttotal‘s initialization:

If I put a breakpoint at this line: var letter = $('#numberAnswerTxt').val(); (inside of getButtons), I can see that the variable "letter" is a string that looks like "3". Strings do not have a property named String, so letter.String is undefined. This is why the TypeError: Cannot call method 'fromCharCode' of undefined is thrown.

So I think that for loop should go something like this:

for(var i = 65; i
