[xsl] Trying to display Summed Average of Grouped Data

Subject: [xsl] Trying to display Summed Average of Grouped Data

Been Struggling for a day or 2 now :(

I know your all gonna cringe at this code because im much of an XSLT'er and tend to work via trial and error....


In Brief im trying to display the Averages of each Column for each individual Days results
so far all the methods ive tried have either led to a "0" or the summing of the Entire collection rather than per day...i tried using variables but found it impossible to manipulate...i fear my xpath knowledge is letting me down ...
any comments hints helpfull tid bits would be GREATLY appreciated
