Need code to remove Signatures (urgent please)

[Former Community Member]

We are using Adobe LiveCycle Designer 7.x and Adobe Reader 7.0.5. We have three signature Fields,

Form5_Dtls.Page3.Sign1

Form5_Dtls.Page3.Sign2

Form5_Dtls.Page3.Sign3

Whenever I open this PDF Form, digital signatures should get cleared. Please share the code for clearing the above signature fields. Kindly reply on urgent basis.
