Hi @ali.safiaddine Try editting the custom node and replacing input types for IN[1] and IN[2] with `string[]` ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/1/f153c535cfe9897f21aad5f150ad76a0379b4e33.png) ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/5/05a4b9a4671526274e25d67650bf13a5b1b87d6d.gif) ---
