My guess would be you're getting the wrong values from the scanner into 
the wrong variables.  The places where you have two calls of nextLine() 
in a row, throwing away both values, seems especially suspect.

Suggestion 1. Print out the value of each variable after you read it in 
with s_scan and show us the result.

Suggestion 2.  Use next(), not nextLine().  Set the delimiter to 
"(\r\n)|(\n)" for newlines.
