How to pass user's value choice from a control inside a calculated field?

I have a datasets with many records of flightids and takeOffMonth. I have created a filter (list drop-down) of takeOffMonth and added it to the controls so that the user can pick which month he wants. Now, I want to create a calculated field that is using the value of month that the user selected. How can I do this? I read everywhere that it’s possible to link a parameter with the control’s selection but I can’t find a way to do it! Can someone describe all the steps to do this? Thanks a lot!

Hi @Fotis_flex,
You’re on the right track here, I think the step that may have been missed is by setting up a parameter instead of a filter control.
So start by setting up a parameter for take off month, then you can add a control for it (like you did for the filter).

Next, you can setup a filter for take off month that is based on your parameter:

Now you’ll be able to use that parameter within a calculated field as well. You can see the article below for more information on that.
