Hi Yusra,

Your array z has only 4 elements. The j-values in the ‘For j element of….’ j can run between 0 and 2000+, due to whatever the match-es find. Inside the For-loop you try to access z[j (3 times). Shouldn't you be using (z[i)[j ?

Ah. And in your simple example you show that your array q.c;z is also a nested array. So you'll have to do a similar addressing there.

Success!
