I do not understand your code.
What should work to let the second function use the first:
ans=function2(function1(input))

Make the variable to global. Check the below code.
function 1() global x; x = 10; x = x+10
return
function 2() global x; global y; y = 0; y = y+20; display(x); return
function test() global x; global y;
display(x);
display(y);
return
