Its always a good idea, when asking a question, to attach the worksheet and also mention if you are using real Mathcad or just Prime and also the version of Mathcad or Prime you are using. This is especially essential when using Prime as all versions of Prime refuse to read worksheets created with newer versions and PTC provides no way to convert Prime worksheets.

If nothing is mentioned in a question, my answers usually will be using real Mathcad (MC 15 at the time being) 😉
