Multiple conditions


I have problems recording multiple condition on single siquence.There are three user tasks with the ‘Yes’ option, they all go out in one exclusive gw. I’m trying to prescribe a Flow condition on the outgoing sequence flow from GW, but it doesn’t work:
${id_1 == ‘yes’ || id_2 == ‘yes’ || id_3 == ‘yes’}

What could be the mistake? could this be a limitation of the free version?

Thanks in advance for your help.
