Start.bat wont work

So I recently added sponge to my mods list for my pixelmon server and when I did so the GUI wasn’t opening. So then i realized that Sponge disables Forge GUI. I realized that i needed a start.bat like the one in the sponge startup document says to use but it wont work is says “Error: Unable to access jar file forge.jar
Press any key to continue . . .”
I dont know why the bat isnt working its made correctly with the correct name for the server forge start up file.
Help…

Share the start.bat file and error here, and we can see what happened. It seems likely you haven’t renamed the forge file correctly.
