Gentlemen,

Thank you both for your endeavors on my behalf.

I have learnt some much from you both that has enhanced my understating of many aspects of Excel and PDF files.

I have to decide if I am prepared to take the risk of someone taking advantage of my labours by sending the data in Excel format or to forsake that for the more secure PDF format.

I do like the spreadsheet array formulas that XOR LX has developed, whether I used that for my own personal use I'm undecided. I have some time to make up my mind as I continue to input data.

Thank you both again.

Regards,
Colin
