How to understand this formula?

[wanzek1]

I am editing someone else's report and I need some help with a formula. Can someone help me understand this type of formula?

WhilePrintingRecords;
Numbervar JobEndSubPhase;
JobEndSubPhase := JobEndSubPhase + {@JobEnd+-}

I understand most of it the part I don't get is this part:
JobEndSubPhase := JobEndSubPhase + {@JobEnd+-}

This field is a formula: {@JobEnd+-}

But where does this come from: JobEndSubPhase

I can't find it in another formula.

Thanks!

It's a variable that is defined within the formula.
It may also be defined in another initialization formula, typically placed in the Report Header.

What I don't understand is that it appears they are adding something to a field:

JobEndSubPhase + {@JobEnd+-}

Say {@JobEnd+-} = 200

JobEndSubPhase + 200

Is the answer 200?

Wanzek1,

This is a Running Total, where each time the formula "triggers" the value of the variable "JobEndSubPhase" is incremented by the value of the formula field {@JobEnd+-} in the same instance.

Example:
[tt]{@Formula in Question} ... {@JobEnd+-}
...... 200 ................... 200
...... 350 ................... 150
...... 450 ................... 100
...... 600 ................... 150[/tt]

Hope this helps!

This helped and I was able to create another one and get it working.

Thanks!
