'SLOPE' and 'LINEST' Formulas do not work ?
Hi CHING CHENG,
I made a few tests and it looks like you are right. Please accept my apologies. I am converting your ticket to a public bug report that you can track.
I also updated your Telerik points. For the time being, I am afraid there is no workaround.
