I have 3 combolist fields ( A, B and C ) each of which has just "No" and "Confirmed" as their only options.
I have one final combolist ( D ) which has just "Yes" and "No" as options. "No" is the default selected item and Index0 in the list.
The user must select "Confirm" all three ( A, B and C ) lists before they should be allowed to select "Yes" in the final list ( D ).
I want to be able to have the system to automatically select and display "No" in list ( D ) if any of the first 3 selections ( A, B or C ) are "No".
I don't have a problem validating if any of the 3 lists ( A, B or C ) are "No" but I cannot get the final combolist to change from "Yes" ( if previously selected ) to "No".
I have tried setting the selected index of (D) to 0 and tried setting the selected value of (D) to "No" but if (D) currently displays "Yes" when any of the ( A, B or C ) are changed to "No" nothing happens to (D).
Am I trying to do something that cannot be done ?
Any help will be gratefully received.
