Selecting the last value of a column

Question

I have a spreadsheet with some values in column G. Some cells are empty in between, and I need to get the last value from that column into another cell.

Something li

Answer 1

I was playing with the code given by @tinfini, and thought people might benefit from what I think is a slightly more elegant solution (note I don't think scripts worked quite the same way when he created the original answer)...

//Note that this function assumes a single column of values, it will 
//not  function properly if given a multi-dimensional array (if the 
//cells that are captured are not in a single row).

function LastInRange(values) 
{
  for (index = values.length - 1; values[index] == "" && index > 0; index--) {}
  return String(values[index]);
}

In usage it would look like this:

=LastInRange(D2:D)
