Thank you for editing the grammar for "myriad".  It's a tough word to use correctly, and usually when I see it it is used incorrectly. No problem, but a little helpful hint I like to use is:  replace the word "myriad" with 'several" and see if it works.  If it does, then you are probably using it correctly. There are myriad puppy combinations! There are several puppy combinations! See?  It's fun. :)
