Can someone help with this javascript exercise. What do I need to do?

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("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 ( 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, I figured it out. If anyone has the same problem.

Change code to this. 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 ( 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."); }

So basically change all || to && and then !== to ===.

It's because var today = 'Friday' and the first if statement has an 'OR' with ||, i.e. if ( money >= 100 || today === 'Friday' ).

I would suggest changing this if statement to: if ( money >= 100 && today === 'Friday' ). The && is the Logical Operator for 'AND'.

Thats what I originally put in. I tried it again and it came back with this error.

Bummer: Hmm. Looks like there is at least one logical OR operator -- that's the || symbols. Those test if just one of the conditions are true.

Since, || means if one of the conditions is true, follow through with the statement. And, && means if both conditions are true to follow through with the statement.

Correct?
