What am i doing wrong?

> restart;
>
> g := .2189750324;


> m2 := 1;

> a := 1;

> c2 := -1;

> equation2 := y = m2*X+c2; 

> area1 := int(equation2, X = g .. a, numeric);

Error, (in int) invalid arguments

 

Can i make an algorithm like this in maple?

w= 4

for k= 1 to 10 do

             for h = 1 to 20 do

                      for a = 4 to 15 do

                               w1= a+hk
