Error encountered during pcell instantiation??

 Hai,

     

    This is the code i have written to read a file and then instantiate a pcell inside an already created pcell:

procedure(mypcell(ruleFile pcellInfo)

  let( (ruleFileTable purposeList mastercv inst )

  ruleFileTable  =  readFile( ruleFile )

;readFile is the function name for another procedure I created to read an file and drop its contents into a table

           foreach(line FileTable

           purposeList = caddr(line)

    ;the table has mainly four elements and I want the third element based on which instantiation has to be carried out

          unless(rexMatchp(pcellinfo purposeList)

           case(pcellinfo

             ("a"

         ;;To Create PCell for “a”

                    mastercv   = dbOpenCellViewByType("test" "pcell" "layout" "" "w")

                  ;mastercv is an already created pcell

                    inst           = dbCreateParamInst(

                                         "pcell" mastercv "a" list(0 0) "R0" 1

                                           list(

                                               list( "w"  "float" 0.5)

                                                )

                                                );dbCreateParamInst

                                         dbClose(mastercv)

                                      ); for case “a”

           ("b"

;;To Create PCell for "b"                   

                     mastercv   = dbOpenCellViewByType("test" "pcell" "layout" "" "w")

                     inst           =  dbCreateParamInst(

                                        "pcell" mastercv "b" list(0 0) "R0" 2

                                           list(

                                                list( "w"  "float" 0.5)

                                                list( "s"  "float" 0.25)

                                                )

                                            );dbCreateParamInst

                                          dbClose(mastercv)

                                          );case

                                   );for case  "b"               

                           );unless

        );foreach

    );let

);procedure

But i am generating errors while i run this code :

Can anyone look into and this find the error in it.....

Thanks,
