Change browse option by calculation.

[IEW]

I have a field (Status) that if it = "Received" un-check the browse box.  Can this be done by calculation using conditional formatting.  TIA

Conditional formatting can change the appearance of a field or text object, but it won't change the stored data. What do you mean by "browse box" -- is it your Status field formatted as a checkbox or a separate field? If it's a checkbox field, what value list are you using?
