Tombles

ok so i did what you said but now it is giving me this error, and i know for a fact i have enough space for this

i am trying to run a forge server off my computer that has a lot of mods. I am attempting to allocate more ram to the server so it can run. However whenever i run the .bat file i created, i get an error that says; "Unable to access jarfile forge-1.12.2-14.23.5.2768-universal". I would appreciate if someone could help me fix this.
