# How do I define the path to an attribute correctly?

Asked by Andras on 2014-10-09

Hello,

I'd like to refer to an attribute in a relevancy expression, but the attribute I want to refer to is some levels higher. How do I go about this?

attribute to refer to: /sample_plot/region

attribute with expression: /sample_plot/trees/samplecandidate

Thanks!

Hi, you have to consider that the expression defined in the attribute **samplecandidate** will have the entity **trees** as context, so it will be evaluated starting from that node.
The expression you need will be something like this: **parent()/region = 'REGION_CODE'**.
Thanks
