Hi
the OR function is used to check if at least one of multiple conditions are
met
=OR(A1=5,B1=10)
will return true if either (or both) A1=5 or B1=10 and will return false
only if neither of them are true.
with an OR fuction you can test up to 30 criteria ... if any one of them is
met then true is returned and false is only returned if none of the criteria
are met.
this function is generally nested in an IF function e.g.
=IF(OR(A1=5,B1=10),"One or more conditions met","No conditions met")
and is used as an alternative to the AND function which requires ALL of the
conditions to be met for true to be returned.
