The lists are columns of numbers (field data from a probe) varying in length
up to 14 cells long.  When I copy these lists into the results section of a
template I can automatically perform different tasks on it (conversions etc)
and arrive with my desired result tabulated on a different sheet and ready to
print off.

The working system I have (mentioned in the previous post) takes account of
a uniformly shaped and well maintained feature so the depth is constant and
the list lengths are all 13 cells long.  From it I can take point readings of
variables at the top, middle and bottom of the column to summarise the data.

The new system I'm working on profiles an irregularly shaped feature which
varies in depth from day to day and even hour to hour.  I'm attempting to
achieve the same effect with this template as I did with the previous one
i.e. a summary of the data from the top, middle and bottom of the column of
data.
