Its seems that you have to read more about scoping (in general and in
Mathematica).
Manipulate automatically generates a DynamicModule which is a scoping
environment.
Take a simpler example

y = m x; (*here m and x are GLOBAL VARIABLES *)

Module[{x =1, m=2},y](*here m and x are local variables having different
names*)
returns
m x
and not the value 2 since the (local) variables of the Module has different
names than x and m

Block is different

Block[{x =1, m=2},y]*here m and x are local variables having identical names
and the global values are stored in the stack*)
returns 2
and m and x are unchanged after the program terminates

Since Manipulate uses DynamicModule (which, for scoping is identical) you
cannot do it this way.

Many thanks Carl, I think this is what I was looking for!
