PHP Code

[amamyoj]

I am using the PHP Code Type in getting the Cummulative sum of the records. But the field is showing 'blank'
this is the query that I am using:
$initialVal = 0;
$currentValue = $initialVal + ([1350]);
$previousSum = ([1350]);
$cumulativeSum = $previousSum + $currentValue;
$cumulativeSum;

and here is what's showing in the debug mode:

Field_1966 is the PHP Code field Im trying to work on and [1350] is the field im getting the value in.

Am I missing something? PLease help.

THanks!
