How to use the good column in a map table

Good morning,

What you are presenting is quite interesting but it is not what I need.  The table you see with the various percentage per distribution type is linked into my model by the time bucket field.

What I would like to do is to use a slicer to select among the distribution.  For example, imagine that I choose the Bell distribution.

So I wonder if there is a way to use only the bucket time field and the bell field, in a lookupvalue function to bring the good percentage into another table

For example, imagine that in a table A is linked to the map table below and that table A contains a Time Bucket field.  Then, if I select the Bell distribution via a slicer, and that in table A a record as the value 40-49%, so I want to bring the value of 0.22 into that table using a lookupvalue.  If a flat distribution is selected, I want to bring the value of 0.1 and so on.

So I wonder if there is a way to do that.

Regards,
