Portal sum-field problem
i've created two test solutions before this ''final'' one, and when i create an external sumfield(OF A PORTAL!) everything works just perfectly!
But in my final solution, it doesn't work at all! When i add rows in the portal, the sumfield adds everything just fine, but when i delete a row, it doesn't ''update''/ it remains the same, until i click outside the portal(sometimes this doesn't work either).... but in my test files this isn't the case...
