What is showing up in your combobox is controlled by the RowSource property. More than likely this is a table, query, or SQL code. A query that aggregates the multiple instances of the field in question down to just one can be done. Please post the SQL. If the RowSource is a table then post the tablename and the fields necessary for the combobox and we will provide the SQL so that you will only have one instance.

this is what is said in the row source:
SELECT [Property].[ID], [Property].[Property_Severity_Class] FROM Property;
so right now it shows something like:
IV
IV
III
II
it reads of course from a table so i guess it takes all the different types... now... how can i stop the duplicates besides from breaking the numbers to a single table.

Click the build button (i.e., "..."
, it will open the QBG window. This allows you to graphically build a query.
This window is divided into 2 parts. Right Click on the upper pane, and select properties.
Change the Unique Values to Yes.
Let me know if that does it.

With the form in design mode, right click the combo box and select properties.
To the right of the RowSource property click on the button with the 3 periods (...).
The Query Builder should pop up.
Your field list will be on the bottom pane and the table or query will be on the top pane.
Right Click on the top pane of the query builder and select properties.
Then change the Unique Values from No to Yes.

Why don't paste the sql to this forum.
Is there a reason why you need both fields.
You could have just the country selected, and select distinctrow to get no duplicates.
Then you could have another combo box for the cities based on the query for the countries.
Let me know.

the thing is.. if i did this after what i wanted i would create a table just for countries... but the thing is.. the person that asked me to do this want the information on one table.. thats why the country appears more than once...
SELECT DISTINCT Environment.ID, Environment.Environment_Severity_Class
FROM Environment
ORDER BY Environment.Environment_Severity_Class;
this is the SQL behind the combo box
SELECT DISTINCT Environment.ID, Environment.Environment_Severity_Class
FROM Environment
ORDER BY Environment.Environment_Severity_Class;
this is the SQL behind the combo box
If this is your SQL the reason you have more than one record for ID is that there is more than one Environment_Severity_Class value for the multiple instances of ID. If you want ID to be Distinct then eliminate the second field.
SELECT DISTINCT Environment.ID
FROM Environment
ORDER BY Environment.ID;

You can keep the information all in one table, without using it all in the combo box.
Here is my assessment (and questions).
In the table there are 2 fields.
Field1 = Country
Field2 = City
Now the source of the combo box is using both fields.
But does it have to?
Also, when you right click on the combo box and select properties, under the RowSource, is there a table name or a sql statement?
