Timer countdown query?

this is probably a silly question, but how could i update the countdown timer script, so it includes years in it, as i want to countdown to an event in 14 years time!

ive tried adding 2 new numbers to the counter, named them as years_0 and years_1, and then tried to update the script as best as i can, but to no avail! :hair:

anybody any ideas on this one? its driving me nuts! btw, im relatively inexperienced in terms of programming, so go easy on me :thumb:
