Range Variable Summation

[TB_10810616]

As per the original post. 

I am encountering the vectorization error that is common when converting old mathcad files to Mathcad Prime 10.  Has anyone updated this sheet for use in Mathcad Prime 10?

Prime isn't using static unit checking (SUC) and as a consequence you have to apply correct units even to zero values:

As an alternative you may use the new "unit" Zero (note the capital "Z"!):

Applying these changes make the worksheet functional

(I edited(deleted) the upper limits of both axis so that all parts of the red trace can be seen.)
