Hi Jerson / HenrikOlsson,

Not sure what happened to my spelling this week either. 'alter' - what is wrong with me! Maybe i should get checked for early onset Alzheimers - ah, maybe not, i can spell Alzheimers!
Having looked through my code, I've realised (English spelling), that concatenation is spelled incorrectly as well, argghhh! Maybe it's the wine - surely not - it can't be the wine - oh god , not the wine!!

P.S. HenrikOlsson, thanks again, that one line of code is beautiful - did i spell that correctly, phew!
