Don't understand why is wrong

var money = 9; var today = 'Friday'

if ( money >= 100 || today === 'Sunday' ) { alert("Time to go to the theater");
} else if ( money >= 50 || today === 'Thursday' ) { alert("Time for a movie and dinner");
} else if ( money > 10 || today === 'Monday' ) { 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."); }

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

if ( money >= 100 || today === 'Sunday' ) {
  alert("Time to go to the theater");    
} else if ( money >= 50 || today === 'Thursday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 || today === 'Monday' ) {
  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.");
}

In the code today is Friday, we initialized that near the top, if you look closely at the conditionals they all have 

|| today === 'Friday'

So the first conditional is checking to see if money is greater than or equal to 100 OR if today is equal to Friday. Since money equals 9 the first part of the conditional is false. But since today is equal to Friday and we are using the OR operator "||" the whole conditional evaluates to true which should be incorrect.

We need each conditional to only evaluate to true if each side of the logical operator is true and we do that with "&&" (without the quotes).

This challenge needs you to debug the code without changing the day. This part of the code should be the same for all the conditionals.

today === 'Friday'

Thank you Julian Gutierrez

Very Kind! Didn't understand the challenge needs.

Still I don't get the solution... I will study harder.

Can you give me a little advise?

Thank you

Thank you Julian

I understood!

I tried to change || with && in a first time but I mad something else wrong, so I tried to change variables messing around with the code.

Thank you for your help
