compare two values

hi @ all

i want to compare the value of <Art_nr> in one row with this, which is in
the row before. if they are similar, i want to show something, if not
nothing should happen.
how can i coompare these values. i tried to do it by count(row) and the
position() function but it does not work.

i hope somebody can help me.

thanx

jan
