Re: A newbie question in XSL - Using variables

> <font color="$use-color">Hello</font>
This should have been  <font color="{$use-color}">Hello</font>
** Notice the curly braces **
  <font color="$use-color">Hello</font>
will not get the  value of the $use-color  variable to the color attribute
of the font tag.It will instead make the value of the color attribute to be
"$use-color"
