Getting int num;redefinition error in while loop

Alb13G (42)
The problem is I'm getting a int num;redefinition error. I don't think whats in the braces is right either

int num = lower_num; --- (causes a int num;redefinition error.)
while (num <= higher_num, )
{
cout << (sum += num);
num++;
}

while (num = lower_num)

This while loop will never ever end (unless the lower number happens to be zero).

This new while loop will never ever end.

Look at lines 13 and 49.

Since you already have line 13, you can make line 49 just
num = lower_num;
