As i said you should explain what you want to do, giving examples of
XML and the XSL you have so far. Like this no one can help.

You must remember that variables aren't variable ;) , once you define
then you can not change their value. So you don't define in one place
and assign in another place. Variables in XSL are variables in the
mathematical sense, not in "placeholder" sense like in procedural
languages, like Java or VB...

I use vars all the time, you just have to be a little more specific...
