#### Topic: How to learn row number in xsl

Greetings, I deduce a line in a template, by default at saving in ml2003 summation of cells put down the explicit formula

<Cell ss:StyleID = "s74" ss:Formula = "= SUM (R [-2] C:R [-1] A C)"> </Cell>

How to change on R [-n] where n the last line?

I.e. how to make that the last line lined the total of all column how to learn an amount of already deduced lines.
