Hey all,

I have a short question on Phoebus:

I have an array PV of uint32's. Each element represents an error counter

for a single channel.

For an overview OPI of our system, I'd like to have a Text Entry widget

displaying the sum of all elements of our array for each device.

Looking at the Documentation [1] I see a lot of formulas in Phoebus for

arrays, but it seems none for calculating the sum of the elements.

I know it could be done via a script, but I was wondering if there is

also another way (e.g. formulas).

Cheers,
Florian
