How to requery data on a form automatically

[whoisit]

I am having trouble with forms
When i change data in a form and run an update query, the query does not recognise these changes and updates the wrong number of fields because of this. How do i resolve this problem so that when i update any data on the form it refreshs itself and so the query can recongnise these changes
THANK YOU

In the required event:

Me.Requery

Take the time to boost your VBA knowledge by pressing F1 over every keyword you are given and don't understand.

 

[whoisit]

And on which property would this code go on
I think it is onCurrent property but not sure
THANK YOU
