Smartproperties Concatenation

Hello 

I can perform  concatenations in a smartproperties file, parts or sheet metal for example, but not in a multi-selection file of welded mechanics.
The property displays the text (e.g., $numpiece&-&$version instead of displaying 01-02)  
The same applies to counters that cannot be incremented. 

Anyone know how to fix this problem or have an alternative? 

Thank you

Hello

Indeed, the SmartProperties interface displays the syntax in the case of a multi-selection, which is normal because the values can be different in the different mechanically welded articles, on the other hand the value created corresponds well to the concatenation of the properties, I use myCADtools 2021 SP2.

Hello 

Indeed, the values created are the right ones, I hadn't even tried to validate...  

Thank you for your answer
