Hi
I have to create a web page for a online quiz which will display same questions in different sequence for each user. Now, I have written code which takes questions randomly every time when user visit that page. User goes to that page by login id and password. I have used random function in query which gives questions in different order for each user. But now problem is when i refresh that page question order changes for the same user. So i wants to disable refresh button. Can you please tell me how to disable it? or is there any other way?
