Checking Exsistance of a Variable?
Is is possible to check the exsistance of a variable?
I am wanting to use checkboxes in a form, but I know that if it is not checked then the variable is not even created. Is there anyway to see if a variable was created or not?

If you're using php you could use...
if (isset($variable)){code to exicute if varible exist;}
Hope that helps!
