Referring to the attached JPG, I am trying to to do two things:
1) Add numeric columns to a collection (no matter what I have tried they always show up as text)
2) Filter by the GrpAll column
I created columns GrpCol, GrpFst and GrpMat and set them = 1 (not "1") when the respective Color, Fastener and/or Material is selected from a checkbox. I also set them to = 0 when the respective box is unchecked. I then created the GrpAll column by taking the average of these three columns (I am doing all of this to set up subsequent filtering).
As you can see, it is working up to this point, but as soon as I filter the GrpAll, the fractions all turn to 1, thus defeating the purpose. Also, oddly if I filter by any of the other three "Grp" columns, some fo the GrpAll fractions flip to 1 and some do not (ex. some 0.3333 remain 0.3333, but some change to 1).
