Paste disabled

I have a workbook to which users will be copying and pasting data from
another workbook. In the workbook to which the data is being pasted is a
range of unlocked cells (a column of 10 continguous cells) and the worksheet
is protected to allow users to edit only these unlocked cells. When trying
to paste from another workbook a column of 10 continguous cells, the paste
function is disabled, so I can't paste into my protected worksheet. Does
anyone know why this is happening???

Emma,
You don't say which version of Excel you're using. I tried this on
Excel 2002 and it worked fine with no problem. I would double-check
the cell locking on your 10 cells. Note that if any of the 10 cells
are locked, the paste will fail for all 10. Also, if they're trying to
insert, it won't work. Also, when you protect the sheet, make sure
that Select locked cells and Select unlocked cells is checked in the
list, but nothing else. Hope this helps!
