Oh, sorry. I didn't read closely enough. You do have
a loop. But your entNew entity structure is not a part
of it. It should be. You need to create a new entity
each time through the loop, and you need to add it
to the shapefile each time through the loop. Your problem
is that your loop doesn't emcompass everything you need
to do in the loop.

You are making one entity and filling that up with different
stuff over and over, before you save that single entity in
your file. You want to make MULTIPLE entities and save
those.

Cheers,

David
