Arash,
there's probably a much better way, starting from scratch
however, to continue this avenue ; try this trick :
goto :
view
toolbars
customize
commands
tools
scrolldown till you see the camera icon
click on it and drag it into your toolbar
close this box
now :
highlight an area of cells on a totally blank sheet and click on the new camera
icon to take a picture
then click on the same area to size that picture and drag it down and right - this will size a picture of blank cells underneath your hidden hyperlink
right click on it to position it over your hidden hyperlink. Right click and choose :
format picture
colour and lines
colour = no fill
line colour = no line
then hide the totally blank sheet you took your snapshot from.
this should basically plonk a picture of blank cells over the top of your hyperlink preventing anyone from clicking on it.
Like I said, this solves this avenue, but I'm sure there's a better way starting from scratch.
(Have a play around with that camera utility, I use it a lot, it's very useful)
hope this helps mate
