1) It does not make much sense to attach a Powerpoint file when all you want to add is a simple picture.
2) Not clear from your text, but I guess its the last calculation line you are moaning about, right?
It should update when you press Ctrl-F9 or it should update automatically when you have "Automatic Calculation" (Menu: Tools - Calculate) turned on.
The failure could be a corruption in your sheet (we can tell as you don't attach it), a bug in the release of Mathcad 15 you are using (can't tell as you don't state which maintenance release you are using - current is M045) or a problem with the implementation/installation on your machine. I guess its the latter, but can't be sure. Have you access to another computer with Mathcad 15 installed and have you tried to load your file there? Have you tried a repair installation. Do you have similar troubles with other files, too?
