Hello,

I tried to create training registration site. I created form named "Registration Status" with microsoft infopath.

I create 4 section control :

PastClass

ClassIsFull

AlreadyRegister

RegisterForNewClass

The problem is every time I give rule about Date & Time and publish to SharePoint Online. When i tried to display the Form at SharePoint Online the section is disappear

for example :

Start > now()

it's work well in SharePoint 2010 but i want to use it on SharePoint Online. Is there any suggestion ?
