Something's wrong with this script. The value in the variable money is only 9. But if you preview this script you'll see the "Time to go to the theater" message. Fix this script so that it correctly tests the money and today variables and prints out the proper alert message: "It's Friday, but I don't have enough money to go out"

script.js
var money = 9;
var today = 'Friday'

if ( money >= 100 && today === 'Friday' ) {
  alert("It's Friday, but i don't have enough money to go out");    
} else if ( money >= 50 || today === 'Friday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 || today === 'Friday' ) {
  alert("Time for a movie");   
} else if ( today !== 'Friday' ) {
  alert("It's Friday, but I don't have enough money to go out");   
} else {
  alert("This isn't Friday. I need to stay home.");

Your else/if statements are only checking for one condition because of the pipe characters (||). If the first condition is false it looks at the second one. '||' means only one condition has to be true for the code in the block to execute; even though money is less than 10, it is Friday so it alerts. You should use '&&' so that it makes sure that both are true.

var money = 9;
var today = 'Friday'

if ( money >= 100 && today === 'Friday' ) {
  alert("Time to go to the theater");    
} else if ( money >= 50 && today === 'Friday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 && today === 'Friday' ) {
  alert("Time for a movie");   
} else if ( money <= 10 && today === 'Friday') {
  alert("It's Friday, but I don't have enough money to go out");   
} else {
  alert("This isn't Friday. I need to stay home.");
}
