Thank you. My confusion is that I'm following along line by line in the training video and the formulas are identical. I didn't see any instructions in the training to use the "toCondition" function. I'll give it a try.

My keep function in advanced training does not work and only returns a ZERO. Below is the code an the image.

$Grade106 = $gcwp.keep('Grade Code',
     isEqualTo('Grade 106'))
$Grade107 = $gcwp.keep("Grade Code",
     isEqualTo("Grade 107"))
$Grade108 = $gcwp.keep("Grade Code",
     isEqualTo("Grade 108"))

0.splice(0.6,$Grade106).splice(1.15,$Grade107).splice(1.75,$Grade108)
