Index exceeds the number of array elements (1) ERROR - not sure why.

I keep getting this error...but don't know why! It's a simple addition equation...for a series of vectors.

My code and excel data file are attached. Thank you for any and all help with this!!

>> WSBModel

Index exceeds the number of array elements (1).

Error in WSBModel (line 179)

Z1PumpTot(t)=S2(t)+S4(t)+S7(t)+S8(t)+S9(t)+S10(t)+S11(t)+S12(t)+S13(t)+S14(t)+...

If you break your script at line 179, you can clearly see the problem. S10 is only a 1x1 array and needs to be a 49x1 like all the other variables. Something is wrong with S10.

I just saw this! Such a silly oversight! Thanks for your time!!
