How do I make something not equal to NULL in ASP

I tried this if statment, and it's nto working:

If IsEmpty(contactEmail) or (contactEmail = "") or (not isnull(contactEmail)) then

<%set rsContact = Server.CreateObject("ADODB.Recordset")
with rsContact
	.open contactValues, objConn,3,3
	if .Recordcount=1 then
		contactEmail				= .Fields("PointOfContact")
	end if
	.close
end with
 
 
If IsEmpty(contactEmail) or (contactEmail = "") or (not isnull(contactEmail)) then 
      contactEmail ="fake@fake.com"
	   
End If
 
response.write "The email is [" & contactEmail &"] and it works YEY"
response.End()
 
%>

Select allOpen in new window

I keep getting this:
The email is [] and it works YEY

I thought it would work, so I added the YEY, but it doesn't OH WY NOT?

I tried this:

if isnull(recordset.fields("PointOfContact").value) then

And I got this error:

Microsoft VBScript runtime error '800a01a8'

Object required: ''

/OPICForms/115/115-confirm_submit.asp, line 53


What coudl it be?

I figure I took the not
if NULL then the email is replaced by fake@fake.com

If not null then it's OK
so that's why altered the if statment from

if not isnull(recordset.fields("yourfield").value) then

to

if isnull(recordset.fields("yourfield").value) then

Is this correct?

I got it!  Thank you all for helping
