Use variables that are defined later on

Question

Hi Guys!I'm having some troubles trying to figure out how to use or call a variable that I define later on a website, for example#meta#The real case is that meta is being used by other functions and since it's already there I want to take advantage of it and recycle, so how can I call or use a variable that where I want to use It, it hasn't been declare yet?
