Launching spreadsheets

[Jim Byrnes]

Using Ubuntu 9.10.

I would like to add some frequently used OO spreadsheets to the 
Applications Menu.  If I fill out the Application dialog when I try to 
run it I get a message saying I don't have permission.  If I fill out 
the Location dialog when I close it the item does not appear on the menu.

An example given in the help is a .txt file being openned with its 
default viewer, seems like the same should be true of an OO spreadsheet. 
I just tried with a text file as in the example and it still didn't work.

I must be missing something, any help appreciated.

Regards,  Jim
