Unable to Copy one field value to another

Hi,

I have loaded UI using xml file. I have to copy the left side field values to right side fields on clicking the checkbox. I have used form’s onchange event to copy fields. All the fields from left are getting copiued to right except the last field Email.When I uncheck the checkbox and checkit again its getting copied correctly.Only the first time its empty. Can any one tell me what is the issue.
