Help With Detecting Duplicate Entries

Hi there,

Im trying to find the correct code that will take my variable (txtcomments) and check it with what is already in my access database field called 'Team'.

If it cant find it already - it adds it to database
If it does find it already - it wont add & redirects

I already have the 'add to database' part and it works fine - can someone PLEASE help me with the duplicate entry check code? Ive searched the net and cant find anything suitable yet. How do i get it to check whats already there and compare it, then act accordingly?

Here is my page so far:-
-----------------------------------------------
<% If Request.Form("txtcomments") = "" then %>
<% Response.Redirect("notext.htm") %>
<%End If%>

<%
'Dimension variables
Dim AO_GB_Connect   
Dim rsAddComments      
Dim SQL_String        &n bsp;    

Set AO_GB_Connect = Server.CreateObject("ADODB.Connection")
AO_GB_Connect.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("table.mdb")
Set rsAddComments = Server.CreateObject("ADODB.Recordset")
SQL_String= "SELECT * FROM List"

rsAddComments.CursorType = 2
rsAddComments.LockType = 3
rsAddComments.Open SQL_String, AO_GB_Connect

rsAddComments.AddNew
rsAddComments.Fields("Team") = Request.Form("txtcomments")
rsAddComments.Update

rsAddComments.Close
Set rsAddComments = Nothing
Set AO_GB_Connect = Nothing
%>
----------------------------------------------

Firstly, thanks for responding :)

I have finally figured it out and for all those who are searching the net in the future and come across this thread in the hope that they find what they are looking for.......well, here is the syntax i couldn't get for two whole days but, now i have :)

SQL_String= "SELECT * FROM List WHERE Team = '"& Request.Form("txtcomments") &"' "

Lol - all those bloody colons and quotes - can get a bit messy eh? hehehe!

Thanks a lot for your help!
