Hi Ellie,

Here's the starter code

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.");
}

and the challenge:

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"

I'll bet we can figure this out once we solve the first conditional:

if ( money >= 100 || today === 'Friday' ) {
  alert("Time to go to the theater");    
}

What change needs to be made for this to make sense? Today is Friday, but we only have $9 - should we go to the theater? When using ||, the whole conditional will evaluate to true if one of the conditions is true.

So, money >= 100 is false, but today === 'Friday' is true, so this first if condition evaluates to true and we'll try to go to the theater with $9 (fail). What can we change so that both of these conditions must be true before going to the theater?

|| is for Or, what symbols do we use for And? All of the if/else if conditions will need to be fixed in a similar manner.

Hope this helps,

Cheers
