Default Avoid duplicates error screen

Hello...

I want to avoid the error page when a record is already entered in the table. I`m going to be more specific...

I `ve got a table called "Table" and the primary key is contains two fields ("Unique_id" and "Name"). This mean that every user owns a Unique_id and is able to insert many records only if he types a different name each time! (I`m saying all these so that I can be more understoodable)
When ever a user tries to insert a "name" for a second time an error screen appears (The page cannot be displayed)...
So I would like a script so that on insert or on update it would check for a duplicate...

                              Thank you in advance!

Hi there,

Probably you will have to check for Unique_Id too, as far as I understand this, it can have different names for single Unique_Id. If that is right, then your query should look something like this.
Code:
sql = "Select Name from Table where Unique_Id = " & UniqueId_Var & " and Name ='" &txtname& "'"
Else it will not let you add "xyz" as NAME again for another Unique_Id.

Hope that helps.
Cheers!
