Placing signature stamp

Hello,

Using Thom Parker's PDF Stamps I created a customized stamp that it was stored in my user area of: C:\Users\Maryam\AppData\Roaming\Adobe\Acrobat\10.0\Stamps.

Using same code from his book I tried to locate the signature stamp on a area of the page which is exactly right location because I measured it.

But what appears on the signature spot is a rectangle with a X connecting each corner to the opposite corner with black lining and boarders.

here is the code:

this.addAnnot({page:1, type:"Square",rect:[72, 180, 216, 216]});

var oStmp = this.addAnnot({page:1, type:"Stamp", AP:"Pe3Rw-AkSLYluHw8jz9iNA", rect:[ 72, 180, 216, 216],rotate:15});

this.addAnnot({page:1, type:"Square",style:"D",dash:[4,4], strokeColor:color.blue, rect:oStmp.rect});

1.  There is no example for the user stamps in the book?  should I move the user stamp into the Acrobat stamp area and rename it?

2:  I am not sure what causes that black boarder rectangle with an X cross appears instead of stamp signature... Any idea?  Thanks in advance.

Regards,
