Invalid Device Variable - Smartthings multi function sensor

Hi

I’m new to webcore, I’m trying to get this to work:

When editing the piston, it says:

“Invalid device variable Mag Lock Engaged”

Can someone give me a pointer on what this means, how I find out what the correct device variable should be?

Thanks

Andy
