Hi,

I am having difficulties with the following piece of code. I wish to decrement the value of $NUMIMAGES on each iteration of a for-each loop. However instead of the desired effect, which is to create links to images based on the name of the page($page-name) and the number of images in each page. I am simply getting multiple links to the same image where $NUMIMAGES still has it's initial value from the count function.

I am sure that, as ever the answer is easy. Can anyone help?

<xsl:variable name="NUMIMAGES"> <xsl:value-of select ="count(/NewsML/NewsItem/NewsComponent/NewsItem/NewsComponent/NewsComponent/ContentItem/Encoding/DataContent)" /> </xsl:variable> <td><xsl:for-each select = '//Encoding/DataContent'> <xsl:element name="a"> <xsl:attribute name="href"> <xsl:value-of select="$page-name"/>.<xsl:value-of select="$NUMIMAGES"/>.jpg</xsl:attribute><xsl:variable name="NUMIMAGES" value="{$NUMIMAGES - 1}"/> <b> Click here for Article!<br/> </b> </xsl:element> </xsl:for-each>
