Update a drop down list when a date is entered



I am building my first PowerApp using a SharePoint site and the user would like the "Stage" of the application (Stage_DataCard1, DataCardValue3) to automatically update when other 'triggers' such as "Transferred to Field Date" (DataCardValue17), "Test Completed by" (DataCardValue19) are completed. These fields will be blank (empty) before the data is entered (Date or text).


"DataCardValue3"  is a drop down list with items -  Choices([@'Log Requests'].Request_x0020_stage)


I need the DataCardValue3 to be either the selected value from the drop down list OR update automatically when one of the trigger points is reached. If a trigger is not met the stage should stay as the last stage.


Is this possible? if so how do I code it? I have had a look online and I think it should be possible but I can't see how - do I use UpdateContext, a plain If statement? Where do I put the code - in DataCardValue3 or where the trigger is entered (DataCardValue17 and DataCardValue19) and under which option?


Many thanks

I know this is an old post, but can you tell me what property this formula was entered into please? I'm trying to troubleshoot it to what I need and am fairly sure I'm not putting it where is should be.
