Hi,
I have a table with a few colums: eg. date, silo1, silo2, total
How do i calculate the total or sum from the colums "silo1" and "silo" ?
eg: total = silo1 + silo2
Primary i want a gauge to show the latest total value.(sum of the two silos)
I am not an experienced developer, but i hope someone can help me her.
Regards dkhp
