Troubleshooting a 'for' loop code - help!

This is my code -

The code is not running through the second for loop i.e. for 'l'. As a result elements of only the first row of all columns are getting updated. Output is:

encrypt =

    44   140   108
     0     0     0
     0     0     0

What did I miss in the code?

You have

                    encrypt(i,j)=temp

but your i is always 1, so you never write outside of the first row.
