Re: [xsl] Increasing a numerical value in a for-each loop

[George Cristian Bina <george@xxxxxxxxxxxxx>]

It seems that instead of

<xsl:value-of select="165 + increment"/>

you want

<xsl:value-of select="165 + ((position()-1) div 2)*35"/>
in the first case on the xsl:when
and

<xsl:value-of select="165 + ((position()-2) div 2)*35"/>
on the otherwise part.

Best Regards,
George
