I'm trying to remember, but isn't "+" used for concatenation? So, yes, 1+1=11. Nope, it isn't, not in XSLT (or more precisely, XPath). I think the problem is the <xsl:otherwise>0</xsl:otherwise>. My guess is that the test is being run on a table with two rows: the first has an index of '1' assigned, so '1' is appended. The next (position()=2) hits the otherwise so '0' is appended, resulting in the string '10'. XPath coerces this string to 10, add 1 to it and get 11. If you had a table with three rows, you'd get 101, four rows would get 1001, etc. If this is correct, just change the <xsl:choose> to an <xsl:if> to get rid of the otherwise clause. It shouldn't be there anyway.
