Assura lvs error!resistor matching problem in opamp

jhasan said:

... when I try to make 1 resistor by putting two resistors in series in layout.
I get an error while doing LVS. It seems that it is not recognizing the series connections of the two resistors in the layout.

Does anyone know how I can fix it?I am using ASSURA for my LVS not diva.
