</round>
</golfer>
Need to put the foll. in a p tag:
<p>Score:r1-r2-r3: allRounds(parScore)</p>
where r1,r2,and r3 are the sums of the score elements within the 1st,2nd and 3rd round; allRounds is the sum of the score elements from all the rounds, and parScore is the sum of all the score elements minus 4 times the sum of all the par elements in the source document.
I know sum(round/score) gives me the value for allRounds. I need help figuring out how to find values of r1/r2/r3. Please help.
