PB Newbie - CurrentRow() is unknown function name

Hi PB Gurus,

I'm trying to get the current row of a column(dddw style) in DW under the clicked event.

I use this:

if (GetRow()=CurrentRow(), RGB(255,255,0), RGB(0,255,255))

But I got Unknown Function Name CurrentRow

If I place this In rowsfocuschanged / rowsfocuschanging event

if (GetRow()=CurrentRow(), RGB(255,255,0), RGB(0,255,255))

It ran. But it throws I'm in  row 1, even if I select another record in my dddw.

Kindly, shed some light on this.

TIA,
