I made a plugin for my server. When you click on a sponge, a Menu appears. If you click on (for example) the diamond block with the name "deposit 5000" 5000 money will go into your bank account. You can withdraw or deposit money (like a atm machine). For the money options, I implemented Vault to make it easier. I put the plugin in my server and then I got an error. I really hope you can help me. Thanks alot!
This is the error:
