How to make an "IF" statement with a Flag input

[wonka1234]

Hi all,

How do I do an if statement with a flag input by a user.  The logic would be:

Flag = False

...

...

If Flag True: 

   Filter columnA for "--".

    Else  leave ColumnA Alone.

Having trouble inputting this into my workflow.

I want the flag section/variable to be inputted by the user.

Thanks.

The flow is not so pretty but hope it works for you.
