I am seeking to use a module sheet to create a sub/function to update a field if it meets certain criteria

I have a table called = "GDV_Rates_Conventional_Sum"

and I have a fields called "No_Of_Risks_Sum"

What I need to do is fill a field if the following occurs

number of No_Of_Risks_Sum is above 100 Then place in 1
number of No_Of_Risks_Sum is Between 50 and 100 Then place in 2
number of No_Of_Risks_Sum is Below 50 Then place in 3

The field to update is called Credibility

Due to the database I am not allowed to create a query, I have to resort to VBA. Any help is greatly appreciated.

You aren't allowed to create a query but you can use VBA, bizarre.:rolleyes:

The only way I can think that you'd be able to do what you want would require you to create recordsets/SQL etc

Are you allowed to do that?

Yes I can use recordset.

I kind of understand that the code needs something like this, but I like most have limitations on my knowledge

sub fillfield
dim db as dao.db
dim tdf as dao.tabledef
dim rst as dao.recordset
dim sql as string

Besides this I think I could manage the Set commands
Will this help at all?

I don't think you need the tabledef, in fact when I think about it you might not even need the recordset.

You could just create the SQL in your code and then use DoCmd.RunSQL to execute it.

Kind of like running a query without actually creating one.:)

Thanks for this, sadly its the RunSQL code I I dont know how to add. I understand that DoCmd is basically the MACRO side of the database, The reason why I can't use the new query build is that the database has been secured down, but I can with a permission access the VBA area

You don't need to create a query to use RunSQL.

Here's a small example.
Code: 
    strSQL = "CREATE TABLE Top500Imported (" & Join(arrFlds, ",") & ");"
    
    DoCmd.RunSQL strSQL
Ignore the actual SQL, it's just the first example I could find.:)

The important thing is building the appropriate SQL statement.

In the above example I'm creating a table using SQL, you'll probably want an UPDATE/INSERT query.
