Stuck on Javascript Data types i & ii number and strings


I'm stuck on the task data types numbers and strings. Task is to enter 3 words in a string which i've done as "red", "blue", "yellow".length each time I enter it its saying Oops try again is your string at least 3 words. I'm not sure what separater should be between each word tried , and ;.


These are actually 3 strings what is meant is something like this:

"red blue yellow"


And in addition to what @haxor789 said about the 3 word strings, for this particular exercise, I found you can't use the apostrophe character....['] Weird, but my code went through when I deleted it.
