Parameter issue

[Anonymous]

I have a calculated column named "Age_Month", which is the how old a part is, in months.  I want to create a custom column that adds the result of "Age_Month" to the value of a parameter.  What am I doing wrong?

1) You must use Measures instead of Calculated Column.

Calculated Columns are not dynamic (Its value will not change with your Slicer value selection).

2) Use SELECTEDVALUE():
Adjusted_Age_Month = Combined_Inventory[Age_Month] + SELECTEDVALUE('Add Month'[Add Month Value]).
