Help! Stuck at Letter Game!

Don't understand what to to at the game where there's different letters all over screen. Am I thick or what? Can someone explain it to me? Thanks for any help!

SPOILER:

bottom of the screen is a word or phrase

my first one was: kate fox

click on the matching letters - in order - in the mixed up ones above the bottom line

if there are two of the same letter you might have to find a different one

the letter drops off the bottom line when you have found it

End Spoiler

find the letters of her name on the bottom of the left screen.

Thanks guys!
