PS Script to find specific text in layer names

Hello,

I have this script to change a layer name according to a document name. However, the script will also add extension ".psd" to the layer name.

e.g.: Document name is orange.psd and after the script is launched the name of the selected layer will change from Layer 1 to orange.psd.

But I dont want the ."psd" suffix. It would be great to import something like find ".psd" and replace it with nothing 🙂

Thanks
