How do I correct this code?

[thick lily]

you can't have else if trailing an else

you'll need to break this into two parts, one for the initial prompt where 1 is required, then another where the other options are available

wouldn't you want that inside the block handling the quit option?

that's because you're already stopping because of the loop condition

no point having dead code

doing a switch on the option may be a bit cleaner
