Not sure why it's red, but

 

shouldn't D(t,u) have at least one "t" in it?

 

and

 

are you really calling columns of arrays?  <2>

The error message should tell you why it is red. What does it say?

 

Please attach the worksheet. (You may have to zip it first, there's a nasty error in this forum still, that often prevents it to recognise valid mathcad files).
