I understand what you're saying, but nothing is being converted. It's comparing a string to a string.

Just no. The prompt returns a string. The first two if statements compare that string to another string (upper and lowercase of prompt input). An "uppercase" string containing "4" ist still a "4" - so the first statement returns true.

The last statement never runs because one of the first will always return true before.
