Pass value of calculated field/KPI visual to parameter for conditional formatting

I have a calculated field created in the dataset (during data prep). The field recognizes a filter I created, showing the correct value on the KPI visual. I’d like to pass the value from the visual (or the underlying calculated field’s value) to a parameter so that I can use the conditional formatting based on that parameter’s value (e.g. show a visual when parameter value is greater than some value). Is there a way to do this?

I tried setting the parameter to a default value against the dataset but instead of getting a numeric value (it’s a count function), I get “All” which I think is due to the User/Group constraint. Any suggestions would be greatly appreciated. Thanks!
