Find text Tint Value

Hi All,

I need to check whether any character have opacity.  I tried the following codings, but it shows all characters as error.

var myframe = app.activeDocument.textFrames; 
for(i=0; i<myframe.length; i++) 
{     var myCharacters = myframe[i].characters;     for(j=0; j<myCharacters.length; j++)     {          if(myCharacters[j].opacity != 100)          {              alert("Error: Check some text has opacity")              }         }     } 

Regards,

Karthi
