You'll need to be a bit more specific. If I got you correctly, you want to take a selected value (by the user) from a combo box and want to update (not insert) it to a table, via docmd.runsql? It'd be easier to help if you could tell us a little more about what it is you are doing.

Dim Mydb As Database
Dim strSQL As String

Set Mydb = CurrentDb

strSQL = "UPDATE tblRefuel SET odometer = " & Me!ComboBox & " WHERE VehID = " & Me!VehID
Mydb.Execute strSQL

Mydb.Close

DoCmd.RunSQL is used like this:

Dim strSQL As String

strSQL = "UPDATE TableName SET FieldName = " & Me.TextBox & " WHERE IDField = " & Me.ControlWithIDValue

DoCmd.RunSQL strSQL

The DoCmd.RunSQL can ONLY be used with action queries such as INSERT, UPDATE, DELETE, CREATE TABLE, DROP TABLE, TRUNCATE TABLE, etc.  You CANNOT use it to return a recordset (i.e. SELECT statement).
