The value created in the lookup table cannot be calculated in the JQL condition of if

[koutarou ishibashi]

I want to calculate the value created in the lookup table in the JQL condition of if.
I would like to make the if condition calculated as follows, but is it not possible to calculate with the if JQL table?
{{#=}} {{done.get("A")}} - {{open.get("A")}} {{/}} > -1 and {{done.get("A")}} > 0
