Not sure of my mistake in here either. Please help :'(

I understand that || is the or statement and using it would make the last "else if" true because today === Friday. So I used && to negate it altogether but that did not work

script.js 
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.");
}

Hi there! You're actually doing terrific and you changed the logic appropriately, but only in one place. We want it to be so that we only go out when it's Friday and have enough money. If we have 1000, but it's Monday, we still don't want to go out. The logic you have where you changed it should be applied to all the previousif/else if statements as well.

Hope this helps! :sparkles:

The issue is with your logical operators.

When you use the operator "||" you are saying only one side has to be true in order for the code to run. In your case, the first line of code will always run because the variable today === "Friday".

However, if you want both sides to be true you would use the && logical operator.

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 >= 9 && 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.");
}
