Sensor Factory not working



I have a sensor factory that is meant to add 2 sets of pages printed values to give me the total. Whenever I set the channel it will only show one of the values

#1:Black Pages printed
( channel (17555,0)  + channel (17553,0) )

Hi there,

The code seems to be fine. Please check whether the Factory Sensor runs in a larger or equal scanning interval as the original Sensors. If this is not the case, the values displayed in the Factory Sensor can be false.

the interval is set the same (every 4 Hours) the results do eventually come in but they don't seem to add up correctly without allowing a long time for it to process
