Hi all.

I have a problem extracting an element form a matrix. I use a procedure from online help:

Extracting Elements
... Press el(A, or A[. You will see ... this works

....
..... Here (matrix) press 3,1→ or 3,1= . ...

When i press comma "," to enter the second number after pressing "=" it stays as comma and i get expression like: picture 1.


My goal is to make it work like this: picture 2.


Thanks for any help.
