Thanks Shamus, this work around did not produce any errors in the version of Seeq my work uses (50.2.3). The only problem now is that it seems that it is not actually providing any empty times.

Thank you Shamus for your quick response! As you may have foretold, I am getting an error when I try to execute the formula using the past() function. Is this something that would iron itself out once the data becomes dynamic again? Or is it possible this is due to the type of data I am using? Here is a snip of my $ft1 function over several days. Currently that function is configured (15min, 4d).

Using only the real time data from a storage vessel's weight transmitter/load cell, is there a way to create some sort of calculator that estimates the date/time it will be empty in real time? The calculation would need to update in real time and use a capsule of the last 15-30 min of load cell data to calculate a linear rate. I've tried using the new forcastLinear() function, but am having a hard time translating that data into an emptying time estimation. I am also unsure if it will update its forecast in real time, as I do not currently have real time data to test it out on. It appears to be simply pulling the historical data of the load cell and copying it. Any help is much appreciated.
