Document control apply on marked row calculated column

[Suma 3]

I have dropdown list M that contains 1,2,3. I use this document property to add an calculated field in the table ${M)*3. This changes the whole calculated column based on M value. I would also like to add an option to only change the marked row on the table. Any suggestion is appreciated

If you wanted to add a calculated column with calculation "${M)*3" where "M" is the name of your document property linked to the dropdown list, you can simply try this custom expression for the calculated column:

DocumentProperty("M") * 3
