Can't send data from controller to view - variable scope problem?

Thank you very much @InsiteFX & @CroNiX for the probable solution and for the explanation.

@InsiteFX: I admit I was less than hopeful with your suggestion (as it didn't make any sense to me) but now that @CroNiX detailed the CI's mechanics it makes A LOT OF SENSE.

Unfortunately I'll be away from the office for another week and I can't give it a go until then, but I promise it will be the first thing I try when I return.
Anyway thank you SO MUCH for this invaluable help! It's most appreciated!
