Color a row with ALV GRID

Question

Hi my friends,
I have written a small ALV Grid where some rows should be colored, dependend on their status in a table. But it's not working and I can't find out, why it is not working. I've already studied all the topics in this forum, which are related to 'row color alv grid', but I can't find the mistake in my code. Is anyone able to find out what is wrong here?
Thanks a lot for your help!

Hi,
I've changed the line to <b>ps_layout-stylefname = 'LINECOLOR'.</b>, but then I'm getting a runtime error 'ASSIGN_TYPE_CONFLICT' in program 'SAPLSLVC in line 2975'...
I don't have any idea what is causing that.
