Python Mapscript :: NameError: global name 'rectObj' is not defined

[Bill Hudspeth]

I am trying to create a rectangle object using Python Mapscript as such:

prevExtent = rectObj(self.prev_minx, self.prev_miny, self.prev_maxx,
self.prev_maxy)

and get the following error message:

NameError: global name 'rectObj' is not defined


I have imported the mapscript module - other mapscript objects are
recognized in different calls throughout my code, so that is not the
problem.

Any other ideas would be greatly appreciated.

Thanks, Bill
