Hi Martin,

That's the right kind of thing, but remember that XPath indexes count
from 1 rather than from 0, so:
<xsl:if test="value[1] > 0">...</xsl:if>
tests whether the *first* value element has a value greater than 0. If
you want to test the second, then use:
<xsl:if test="value[2] > 0">...</xsl:if>
You don't need to do ./value -- that just tells the processor to go
from the context node to its child value element, and all relative
paths go from the context node anyway.
Also note that value > 0 tests whether *any* value element child has a
numeric value greater than 0, rather than testing the last one.
Cheers,
Jeni
