Question: Assignation in a for loop does not work

I want to load some specific constants at the beginning of my document. I load the ScientificConstants package first. Then I use a list of names of the constants I need. But the assignation in the loop does not work. Only the value and the units appear in the list, but they are not assigned to the letter. See the document included for more details.   Using_the_constants_.mw

Thank you in advance for your help
