I think what David tries to say is that you want e.g.
   ../../fmp:COL[3]/fmp:DATA[$parent-position + 1]
instead of
   ../../fmp:COL[3]/fmp:DATA[$parent-position]

(and the same for the other values.)

Or you would need to use
   ../../fmp:COL[3]/fmp:DATA[position() >  1][$parent-position]
   ../../fmp:COL[4]/fmp:DATA[position() >  1][$parent-position]
   ../../fmp:COL[5]/fmp:DATA[position() >  1][$parent-position]
and so on to work in the same range your for-each works with.
