Filter a table to then change a DAX formula

[RichyL1980]

I have a Postcode Table with Lat and Lon I want to be able to filter this table down to have the result show as number 1 so it can populate a DAX formula I have to Calculate the Miles from Point to Point

Miles = ACOS(COS(RADIANS(90-Sheet1[Supplier Lat])) * COS(RADIANS(90-LOOKUPVALUE('Customer postcodes'[latitude],'Customer postcodes'[id],1))) + SIN(RADIANS(90-Sheet1[Supplier Lat])) * SIN(RADIANS(90-LOOKUPVALUE('Customer postcodes'[latitude],'Customer postcodes'[id],1))) * COS(RADIANS(Sheet1[Supplier Lon]-LOOKUPVALUE('Customer postcodes'[longitude],'Customer postcodes'[id],1)))) * 3959

This is statc data.This is the customer that needs to be selected

I have a filter on the customer so when one is selected it needs to change the miles in the Dax.

hi, @RichyL1980 

You should know that calculated column and calculate table can't be affected by any slicer. you could create a measure instead of column.
Notice:
1. Calculation column/table not support dynamic changed based on filter or slicer.
2. Measure can be affected by filter/slicer, so you can use it to get dynamic summary result.

Thats for the links but a measure will not do what I require. I dont think what I am trying to do is possible but thank you all the same.

I will always have the problem with this one, Adding a measured column still would not produce the required result.

Thanks for trying to help though.
