​I have a form connected to a graphic. The form has combobox1 connected to udt1 having one column for race number and one column for xml path. The combobox1 has the race number and when selected it provides the path for the appropriate xml file. This form and graphic was working well. However I needed to add an additional information to that graphic from another xml file. I created combobox2 connected to udt2. When combobox2 data is selected the appropriate xml file is selected. After creating combobox2, combobox1 and combobox2 data selections are working but could not get the XML path.
