Want to use MAX not LAST

In a form for viewing or entering records to an Excel sheet, I have successfully used the following for adding a new record, adding 1 to the EmployeeID of the last record:

If(EditForm1.Mode=FormMode.New, Last(LikeVideo).EmployeeID+1, ThisItem.EmployeeID)

But since the last record may not be contain the max value in that field, I decided to use MAX function.  I tried all of the following, with no success:

If(EditForm1.Mode=FormMode.New, Max(LikeVideo.EmployeeID)+1, ThisItem.EmployeeID)

If(EditForm1.Mode=FormMode.New, Max(EmployeeID)+1, ThisItem.EmployeeID)

I even tried (which I rightly did not think would work):

If(EditForm1.Mode=FormMode.New, Max(LikeVideo).EmployeeID+1, ThisItem.EmployeeID)

 

Max seems to be a valid function, but I am out of ideas.  Help!  I'm sure it is simple, but as we all know, everything in computers is easy, but often not intuitive. 🙂

Try using Sort on the table to ensure your IDs are in order, then use First or Last as appropriate to pick the one you want.

I suggest using First(Sort(LikeVideo,EmployeeID,Descending)).EmployeeID+1.  Make sure that EmployeeID is a number type column. Max() and Last() are not delegatable, meaning that once you exceed the maximum number of items (500 default, 2000 maximum), the result will not be correct.
