Sharing variable between two robots multimove

Naturlight

Hello,
Simple question but
I have two robots on multimove system. I want to share the variable speed between the two robots (same parameter)

How to proceed ?
Robotstudio tall me all the time it doesn't know "pers" variable from the other robot ..

Here below some example with toto string



Thank you

you need to declare it in both tasks the same. each variable in its own task.
