So generateOTP() should give me a random number and it will display above the text "Enter the Number Above" it works but after I add my second function it disappears. What the program is supposed to do is display a random number, then you input the number next when the number matches the random number given it will give a message "Your answer matches the number above" and otherwise Your answer does not match the number above." Please help

You have your else
keyword within the if
statement. It should be:
if (condition) {
// do something
} else {
// do something else
}
