Re:  Problem with count iterate values
Hello
I do not know the difference, but it seems that I can not use this header:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="exsl"
version="1.0">
Tag form template David Carlisle:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
               xmlns:exslt="http://exslt.org/common"
               version="1.0">
was accepted but this one in my system display nothing. His template
works correctly.  My system don't support exslt well. I wonder if it
is a question of this declaration or  function of exsl which you used.
I don't know which may be reason of this problem.

Static columns are OK. I lost many hours trying to make recursive
columns, and it is quite good idea for this problem.
Kind regards.
