What are you trying to do on Submit ?

It looks like you are subtracting accumulated amount" from a random parking meter ?

What list is it you want to work on ?

Yes I want to subtract the value in the "accumulated amount field where the â€śDueparkingmeter valueâ€ť is in line with it. As I "Input the Dueparkingmeters value & press Submit

It will subtract a random parking meterâ€™s Accumulated Amount at the moment.

Will there be many Parking meters to sum up ? Or just one ?

There will many, many more " Dueparkingmeter actually

But the current problem is that when I Input the values in the "Dueparkingmeters it subtract any value from the fields in "Accumulated amount instead of what I required like

For Exapmle when I input value 200 from "Dueparkingmeters it doesnâ€™t subtract 10 from "Accumulated amount thats the problem

So you want it to find all Parking Meters that match the DueParkinMeters and subtract the total ?

To find all Parking Meters that match the DueParkinMeters and subtract the Accumulatedamount from the Userâ€™s the Current Userâ€™s "AvailableBalance total

Where Dueparkingmeter is inline with Accumulatedamount

Remove the â€śonly whenâ€ť.

Then change the Search to add the â€ścontains input types hereâ€ť as a constraint.

Change â€śrandom itemâ€ť to â€śfirst itemâ€ť.
