problem with dbFindProp()....?

Hi, All! I am using Cadence IC514 version.
I found a code which increases the parameters by a given factor in schematic.(i.e width and length etc...)
My problem is as follows...
I have two instances pch_25_mac with
              1)    "w"="5u" and "l"="500n" and                 2)    "w"="5u" and "l"="280n"(this is the default value for this parameter)
dbFindProp(inst prop) is returning it's id on first instance but it is not when the parameter value is default value.
How to resolve this problem...
Here is the code that I have got....

procedure(CCS_ModifyWL(lib cell factor "ttn")
let((cv new propId)
 cv = dbOpenCellViewByType( lib cell "schematic" "" "a")
 when( cv
   foreach(inst cv~>instances
     ;foreach(prop list("w" "l")
     cdf1=cdfGetInstCDF(inst)
     foreach(prop list("w" "wf" "l" "wr" "lr" "sumW" "sumL")
     if(member(prop cdf1~>parameters~>name) then
       ;when(propId=dbFindProp(inst prop)
   propId = cdf1~>prop
         new = sprintf(nil "%g" cdfParseFloatString(propId~>

value)*factor)
         printf("Changing instance %s property %s from %s to %s.\n"
           inst~>name propId~>name propId~>value new)
         dbReplaceProp(inst propId~>name "string" new)
       );when the prop exists
     );foreach prop
   );foreach inst
   ;dbCheck(cv)
   ;dbSave(cv)
   ;dbClose(cv)
 ); when the cellview was opened ok
);let
);procedure


Thanks in Advance

        I am very very Sorry, for the mistake made to the previous message ... This is the actual code which I have got...

        procedure(CCS_ModifyWL(lib cell factor "ttn")
        let((cv new propId)
         cv = dbOpenCellViewByType( lib cell "schematic" "" "a")
         when( cv
           foreach(inst cv~>instances
            foreach(prop list("w" "wf" "l" "wr" "lr" "sumW" "sumL")
            when(propId=dbFindProp(inst prop)
               new = sprintf(nil "%g" cdfParseFloatString(propId~>value)*factor)

                 printf("Changing instance %s property %s from %s to %s.\n"  inst~>name propId~>name propId~>value new)
                 dbReplaceProp(inst propId~>name "string" new)
               );when the prop exists
             );foreach prop
           );foreach inst
           ;dbCheck(cv)
           ;dbSave(cv)
           ;dbClose(cv)
         ); when the cellview was opened ok
        );let
        );procedure


        Thanks in Advance
