Could someone tell me why 'g' is undefined?

You only define g if age >= 8.
Perhaps you want an "end" after you assign a=0 after your age test.

Not all options for your if-structure will result in defining g
if age<1
a=.4;
else
if (age>=1) && (age<3)
a=.6;
elseif (age>=3) && (age<5)
a=.7;
elseif (age>=5) && (age<10)
a=.5;
else
%only here g will be defined
