Hi,


This can be achieved by using custom javascript. We can enable the button based on the position of the scroll bar. Please try the script below:


document.getElementsByName("licenseAgreement")[0].addEventListener("scroll", checkScrollHeight, false);

function checkScrollHeight(){
    var textElement = document.getElementsByName("licenseAgreement")[0]
    if ((textElement.scrollTop + textElement.offsetHeight) >= textElement.scrollHeight){
        document.getElementsByName("button")[0].disabled = false;
    }
}
