Help with Everything be True challenge

Not sure what’s wrong here, I am not able to use the 2nd argument to reference the property in the first argument but if I were to use the exact string, I can reference it. I have reset the browser and tried it in IE and Chrome but still can’t figure out what’s wrong. Your help is appreciated. Thank you

You can’t use dot notation like that. If you want to access a property using a value stored in a variable, you have to use bracket notation:

collection[0][pre]
