How do you force MS Project to determine the Start date of a task that should start upon the earlier completion of 2 other tasks? Task C should start upon the completion of Task A OR Task B, whichever finishes first. Thanks. Saving Changes...

Because Project is generally a "push" rather than a "pull" type schedule tool, you will need to use a simple slight-of-hand and repeat as needed.
I accomplished this by using Date1, 2 and 3 fields. Copy the finish date of Task A and Paste-link in Date1 of Task D. Then copy and paste-link Finish of Task B in Date2 of Task D. In date3 of Task D use customize field and use the following formula: IIf([Date1]<[Date2],[Date1],[Date2]).
Finally copy Date3 of Task D and paste-link to start of task C, with no other logic. Now when you change the duration of either task A or B, C will be the lesser of A or B.
That's the best I can do on-the-fly! Saving Changes...
