Rounding

[kicken18]

I am having some problems with rounding numbers. I have a DB using forms and i want the user to enter a weight and it rounds to the nearest half KG, so either ?.5 or ?.0 depending on what the number is. I know i can enter a range check in the table validation or say => 5 AND <= 10 but i am stuck on the rounding validation. I think this must be enterd into the text box of the form but as to what the syntax would be i am lost.

Thanks
Chris
