Dear all, I would like to create a message box in MS Project that appears once the date of a particular milestone in a Plan of Work has changed. In this example, I have a task finish date that is the end of the project "Project End". While working on updates to the Plan, I would like a message box to appear if the date of "Project End" is later than its value when the file is opened (i.e. the changes I've made have made the Project End date shift later). I would like the message box to appear at any time during the editing or updating of the Pland of Work until the plan is saved. In the Plans of Work, there can sometimes be hundreds of tasks and I don't always remember to check the end date. I know that I can chage the format of Changed Cells but these changes are removed once the next change is made.
Thanks for any help.
