Hi, I have a requirement, when I click on a button the crm ribbon, it opens a html webresouce, and needs access to crm form fields. I have written javascript inside html webresouce to retrive values,
so when I use,
var fieldvalue = window.parent.Xrm.Page.getAttribute("name").getValue().
I get a runtime error saying, 'Page' is null or undefined. please help in resolving this.
