Subtract the data from two dynamic tables

Hi anasofia92500 ，

Based on the information you provided, it appears that your slicers are created from a field parameter table composed of measures.

This field parameter is also used in the matrix.

If so, what you need is the difference between the two slicer options (two measures).
You can create a new measure equal to two slicer options (two measures) subtracted to get the target result.

Below are the test results.

Please see the attached pbix for reference.
