Hi, I was just wondering on how I could get a whole column full of integers
and added them up and display that total? I currently use a for loop to
display the whole column in a table, but I wanted to add all those numbers
up.
Thanks.

Dave,
You're v. close to an answer. Think about it a bit.
Initialize a variable before your loop, setting it to zero.
$tot = 0;
In the loop, add the amount to that variable,
$tot += $num_to_add;
OR
$tot = $tot + $num_to_add;
After the loop, echo $tot.
