Hi Sam,

Could you repost using plain text please?
As you can see below the htnml/rich text option destroys the formatting
of the data and code making it near impossible to read.

As a guess, the problems you are facing is probably that you are
throwing away (or overwriting) the results inside a loop somewhere
and only the last line gets kept. You probably need to create a list and
append each result to the list.

But without being able to read your code that's only a guess.
