Linked object property filled by conf. table.

[Kuzma30]

The situation is such that I need to change in the assembly, the body to which Link refers in accordance with the configuration table.
What I have tried.
Created a configuration table with 3 options HGR15, HGR20, HGR30. Wrote a logical expression that substitutes the correct name that corresponds to the variant. Brought this line to the form "Body00x (HGRxx)" and tried to insert it as an expression for Linked Object properties.
But it show errors... Any variant to resolve this problem (for me) another way?
