Macro with Control Parameter not updating

[Nuno_Meneses]

Hello all, 

I have a batch macro with a control parameter to update a field to run several workflows. However I can't make it update the field like it as supposed to. I would like to hear for you if you know any solution that I can try.

I have attached the macro "Runner" and a test workflow. 

Thank you.

@Nuno_Meneses Can you please export your macro instead? I downloaded it and opened it and the first tool in the macro doesn't show up.
