```auto
/*data.csv looks like this-
header
1,
1,
1,
*/
Table table;
table = loadTable("data.csv","header");
for(int i = 0; i < table.getRowCount();i++){
TableRow row = table.getRow(i);
int a = row.getInt(0);
println(a);
}
```
I know that this is a very basic misunderstanding of the data type, but I’ve spent way too long on this problem and I don’t have anyone available to ask. How would you find the sum of (a), all rows in column (0)?

Declare b before the for loop and say
b = b+a; in the loop

Hello @syzygy,
Here is an example with products:
It will have to be adapted for sum.
Make use of `println()` statements to help understand what your code is doing.

Thanks, that helps. println(b) returns
1
2
3
I understand that the operation goes something like this:
1 = (0+1)
2 = (1+1)
3 = (2+1)
But what I really need is for the sum to be an int with a value of 3. I feel like the Table class can be really powerful, but there’s something that I’m not conceptually grasping about the data type

println gives the correct result only after the for loop
During the for loop it’s going over the rows and adds
data

Not sure what you are getting at
Try with other data in your csv
