Invalid Calculate for Bind Attached to 'relevant'

[jake_eizy]

I am using survey123 connect. I have portion of the form that calculates based on inputs from above. I also have a warning appear if the calculated value returned is above a threshold. I believe the error I am getting is because the pop up warning in the relevant column does not know how to interpret the equation. How do I tell the pop up warning in the relevant column to be "inactive" until a value is calculated? 

SCFM_Convert has a calculated field based on inputs above. I then use scfm_warning to look at the SCFM_Convert result and decide to appear if it is above the threshold. 

Error message "Invalid calculate for the bind attached to "${SCFM_Convert}": Unexpected beginning of path in expression <insert equation>"

I have attached a portion of the screen shot for my xsl form used to build the the survey.

In Survey123 the '/' is not correct for division, you need to use 'div'.
