Hi @ashokpoluu1, can you send us an e-mail to support@aimms.com so we can go over your project together? At first, I can’t think of any reason on why your checkbox is being empty. 

@gabiservidone  it sis checkbox in table and Button is used to navigate to another page using page link. Let me know if  this information is not sufficient

Hi! which check button you are refering to? Checkbox in a table, multi-select, scalar? Do you have any procedure running when opening the new page?
