How we can recognize an empty value of ms access field.
suppose :
[CODE]Dim empVal, empVal1, num
num = 0
empVal = Recordset.Fields.Item("subj").Value
empVal1 = Recordset.Fields.Item("org").Value[/CODE]
here empVal = "" and empVal1 = "" i. e. in the database there are no value i.e. empty
so if i wrote
[CODE]If ( (empVal = "") AND (empVal = "") ) Then
num = num + 1
response.write num
response num
end if [/CODE]
here value should show "1"
But it is not entering within the if condition.
So, how can we evaluate the value of empty

IsEmpty() or IsNull()
NULL and actualy empty are different then ""

Poor planning on your part does not constitute an emergency on my part.
