You need to define a NAME for the range and use that in the validation...
Navigation INSERT-Name-Define
Enter the name in the topbox and range in the bottom and click ADD

Pl. click ''''Yes'''' if this was helpful...

I tried using the Data Validation in order to have the 'user' select from a
range of values. The list is in a hidden sheet within the worksheet.

However, the problem is that when selecting the Source, it does not allow me
to browse to another sheet.

In order to work around this I do a bit of "copy and paste" to get the
values of the reference sheet before copying to the 'Data Validation',
however it is a bit cumbersome :)
