Fuction definition

Hi

When I try :
------------------
p = 1;
f1[x_] := p Sin[Pi x];
p = 2;
f2[x_] := p Sin[Pi x];

f1[0.5]
f2[0.5]

Out[26]=2.

Out[27]=2.
-----------------
When I use = instead of := it works OK.
Why ?

It is safely to use "=" in function definition ?

I have to integrate and differentiate such function in the future.
In my case function depends on about 20 parameters, which are calculated
three times, (I want to obtain three functions)

I'm not sure is this good idea to use '=' ?

Regards , Olaf
