You have a folder name in your save statement of 08DC which doesn't match
what you were saying in the description. I think you have your backslash in
the wrong place. (In fact, you also have a second DC08 and a second use of
mnth. Much more stuff than you have in the description.)
As a matter of principal, do not construct something like a file name
directly in the parameter of a call to a method. It makes things much
harder to debug.
Create a variable and put the constructed file name in there, then check it
(e.g. using MsgBox or just view it in the VBE), and then use this file name
variable in the save call instead of the expression.
If you'd done it that way, you would almost certainly have spotted the
problem immediately, yourself.
