Use variables that are defined later on

[IxDelga]

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

<cfoutput>#meta#</cfoutput>

<cfset meta=1>

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?

This is a very very fundamental question about how programming & web apps are concerned, so best you read some docs:

You can't.

Yeah... I noticed that, well what I did was that I moved my function after the variables are declared... thanks guys!
