How can I make a signature field value on page 1 repeat on second and third pages of my form

Hi all,

I am designing a form; it has a signature field that when it is signed on the first page, should repeat on the second and third pages.

I have a signature field on page1, and textfields, named textfield2, and textfield3, on pages 2, and 3.  The following is the codes I have on Change event, but it is not working;

try{

    var getSigField = event.target.getField("form1[0].Page1[0].signature_BUTTON1[0]");

    var oState =getSigField.signatureValidate();

    // Get the current field's signed state.

    if (oState != 0){

    form1.Page2.TextField2.rawValue = form1.Page1.signature_BUTTON1.rawValue;

    form1.Page3.TextField3.rawValue = form1.Page1.signature_BUTTON1.rawValue;

    }

    }

      catch(e){app.alert(e)}

I do not know why the signature field on page 1 works perfect, but the values are not pass to the fields on pages 2 and 3.

I need help from anyone out on this forum. Thanks

Tammy
