Help needed here in any way as im quite stuck!

I have a customer base that i want to contact every couple of months and record when i do. this is always being added to too.

my plan was to use an INDEX to show the people to contact that week, then i wanted to update those rows only with todays date when i contacted them without going back to my data sheet and try and find all

the fields are... and i want to add the date to "contact letter1", then next time "letter 2" etc
Surname Flat number Building name Number Street Town County Post code
contact Letter 1 contact Letter 2 contact Letter 3 contact Letter 4 i hope that makes sence, any other idea on how to do this would be great.

thanks in advance.

Big Jeff
