Array Element Formulation

[Qshake]

All - Please see the attached pdf. I'm having difficulty getting the following to work in Mathcad. The error I get is this array index is invalid for this array. The frustrating part is that I've done this before in a different Mathcad sheet and it's worked fine. Any ideas as to what I'm missing?

Thanks!

The actual sheet would have been more useful.

You have (L-d[i)*d[1 in the integral. Is that intentional? However, the problem looks to be an ORIGIN error. Array indices start at 0, unless overridden by ORIGIN:=something else. So, you using 1;9 for the 9-element vectors, but the indices should run from 0 to 8

IRstuff - I'd hoped you'd still be around on the site to reply. I changed the i=0 and n-1 and the expression worked. So thanks for that! I'll have to figure out why it worked on the other Mathcad sheet as the variables all appear to be the same.

Thanks again,
