"Any recommendations?"

Recommend that -- at a minimum -- you tell us *HOW* "it doesn't seem to work." That will make making recommendations easier. As it is, some of us (assuredly including \me) would have to download your data snippet and your code and execute it to ascertain what you probably already know.

You probably don't want to make the price of offering assistance that high; unnecessarily high!

And BTW, if the phrase "doesn't work" means "throws errors or warnings" you need to mention what they are... and if the phrase means "dies silently" then you need strict and warnings and either debug or some debugging-print-statements in your code.

HTH
