How to Extract values with indexof and substring?

[YooOwnIt]

In the console I'm trying to get the code to prompt for questions (first name:, etc.) and for me to be able to fill those questions accordingly. Nothing shows up in the console message and it just crashes. I assume it's because I'm using the indexof and substring methods incorrectly.

Does anyone know how to make the console prompt for the questions and for it to extract the values properly?

I know I can do the split method, but I'm actually submitting this to an automated grader which does not support the split method
