The data table below has been generated on Excel and then copied to JMP

I'd like to perform a logic test which involves the following steps -
1. Ordering the "Parameter" column in descending order
2. Checking whether each of the values in the "Parameter" column is greater than 25% of the highest value in the Parameter Column. If it is - the logic column should display "TRUE" else "FALSE".
I don't know how to reference a cell in the formula on JMP like you can on Excel (e.g. - $A$1)
