"Due in Two hours" means its probably already to late.

But even if, its not easy to help. Whats the actual Problem? You dont tell us.

And your code doesnt make sense to any of us.As it wont work without your ADbutton class.

for (int i=0; i<ins; i++); // This line does nothing.

for (int j=0; j <cols; j ++); // This line also does nothing.

buttons[i+j*lins] = new ADbutton(10 + (160*j), 10 +(i*40), 150,30,7,str(i+j*lins)); // this creates a single button.

Maybe you wanted your for loops to actually do something? Then you should do this:

for (int i=0; i<ins; i++){ // Use a {, not a ;

for (int j=0; j <cols; j ++){ // Use a {, not a ;

buttons[i+j*lins] = new ADbutton(10 + (160*j), 10 +(i*40), 150,30,7,str(i+j*lins));

}

Maybe we should add why the first lines does nothing.

If you write a loop without braces you cant end it with a semicolon. Otherwiese nothing happens.

If you just write for (int i=0; i<ins; i++) without ; at the end then the following line gets executed.
