in my experience counts and mappings don't work together very well. A
preceding count is always used for the first command in the mapping only.
So what happens when you enter

4<F11>

is that Vim converts your count to an address for the command-line,
which effectively results in

:.,.+3call VMA()|:bn

In your mapping you first have to remove this address and "move" the
count to the front of the command :bn. The count is stored in the global
variable v:count. There is an example at :help v:count which can be
adopted:

:nmap <F11> :<C-U>call VMA()<bar>execute v:count1 . "bn"<cr>

Note that I removed the superfluous second colon and that instead of
v:count I used v:count1 which defaults to 1 if no count was given.

Regards,
Jürgen
