How to calculate area for a given schematic

IC Layout

 Hello! Every body, I am using cadence IC514 version and a 90nm PDK kit called "gpdk090".
My intention is to calculate area for a given schematic.
I wrote a procedure called "area()" which will calculate area in the current level (means for transistors, capacitors and resistors only).
Now I need to call this procedure for every instance which is not a transistor,cap or a resistor.
I wrote something like this........................
foreach( inst geGetEditCellView()~>instances
    when( inst~>purpose == "cell"
        if( inst~>libName == "gpdk090" then
            area()
        else
            label:
            cv1=dbOpenCellViewByType(inst~>libName inst~>cellName "schematic")
            foreach( inst1 cv1~>instances
                when( inst1~>purpose == "cell"
                    if( inst1~>libName == "gpdk090" then
                        area()
                    else
                        goto label
        ]
Can some body guide me in this way...
                Thanks in Advance...

  •  Really, I tried a lot.......Still I am not getting how to access the area of individual block area which is in tolevel schematic .

    In my every attempt the area is being adding to one variable only..I tried to have one more variable to add block area still results are not satisfactory.. Also I made three procedures same thing happening..

    If you don't mind can please send me a code snippet which will guide me in accessing the whole block  area ....

    Anyway I am getting the total area of given schematic perfectly...but it's only my part of intention... 

    thanks & regards
