Some type of function Error

[Sarah409]

Hi,
I wrote a function to find the sum of an equation, but the output I keep getting is 0, when it should be 784 when x = 7. Can anyone tell me what is wrong?

Line 19 needs to be double i = 0;

while(i < someNum)

You need to initialize your loop control variable.
