Perhaps a VLOOKUP table would fill your needs.

Thanks - I'll try this, but while I am on the subject of spreadsheets and
formulas - can you show me the the idiots way of creating an auto complete.
A lot of my records have a unique reference number, but may contain the same
sort of information similar to another record
ie name (unique), house number (seperate cell)
Street - its here where I could do with the town, county, region auto
filling in

Many thanks

Hi!

You can use Data Validation for this.

Assume the range in question is A1:A5.

Select that range, A1:A5.
Goto DataValidation
Allow: Custom
Formula: =COUNTIF(A$1:A$5,A1)<2

You can create your own custom error message if you want by clicking on the
Error Alert tab.
