Multiple conditions

I have been working on this exercise for a while, for my looks correct. The correct message is displayed, but I got this error message: It looks like there is at least one logical OR operator (that's the || symbols). Those test if just one of the conditions is true.

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

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

if ( money > 10 && 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("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 Yonara

} 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.");
}

So you have an OR so if either statement is correct it is going to print today is Friday. money is always going to be less than equal to 10 since above you tested for money greater than 10 above (remember if else statement end after finding a true statement). So definitely need an AND. Now since our first statement says "It's Friday, ..." do we want to test for money NOT EQUAL to 'Friday'? I think that needs to be EQUAL to 'Friday'.

Hope this helps and helps you understand. Keep at it!
