Article 3

Correct. Using remote viewer but making a custom template.

Passing this query string SumStats=NumPositiveOne

and need to print the count in this loop.

xsl:for-each select="$SocialObjects/CommunitySocialObjects/List/SocialObject"
/xsl:for-each

I know in a system page we call it like this
TPGroupSumStats TP_StatTypes="NumMembers|NumSocialObjects|NumComments|NumPositiveOne"
