How to modify this script to work on server or client?

Howdy all,

This is my first post on here.  I usually research and trial and error my way through PC related things, but I'm am completely stumped.  I have background in playing in C# with Unity3D.  I have not actually done much with Java and trying to learn to code and mod Minecraft.  I have a workspace on MCreator with literally the only thing I have added is a plant mod for testing and I'm trying to get it to work on a multiplayer server.  I have completed the plant correctly because it works fine in single player.  Here is the script for the plant.  I have played around with changing the ".CLIENT" to server but nothing.  Can someone show me what needs to change to make this plant spawn and behave like a regular plant on a server please?
