Hi,
My recommendation is to go to edit mode for the Cost Centre column and try the formula below and changing type as Label
=If(left(Cost Centre,1)=0,Cost Centre,"0"&Cost Centre)
Based on the fact that some of our Cost Centre start with "0" and some do not, this worked for me. And the formatting error that ignored "0" had an impact on my lookup values depending on Cost Centre. I gave it a try, and it was successful for me.
One other thing is you have to change the column type to Label from numeric across dataset.
