I keep getting the below error: 

M:\view\testvob>cleartool co foo.c
cleartool: Error: Element "foo.c" is already checked out to view "<no-tag-in-region>"

how do I solve? 

Hi Riley,

You asked:

   "I keep getting the below error:

M:\view\testvob>cleartool co foo.c
cleartool: Error: Element "foo.c" is already checked out to view ""
how do I solve?"

The answer is:

   You should either checkin the the file foo.c (to commit the change) or uncheckout it out (unco) to toss the changes.

Also assuming M: is your MVFS drive it is probably not a good idea to create a view called "view".  that name might just cause confusion later on with you will see messages like '... view "view"'
