Thank you for the information, I tried this and it solved the part about the duration changing, but now the Resource percentage won't change, but I need it to change. So, for example, if I have a task for "Mike" set for 1 hour, the Resource Name column says Mike[13%]. If I change the task to 2 hours, I want that column to say Mike[25%], but it stays at 13%. Is there any way to fix this part too?
