Coding Help via scratch and roblox

Hi, so I’ve been wondering if anyone here knows Lua or Scratch code better than me because I’m planning on starting a game on Roblox fairly similar to Rail Sim Universe and I’m using Scratch to build the UI for practice, and I’m having issues with the horn function there’s no official release date yet because its a solo project but I’m just wondering if I could get a little help with the coding since this is expected to be my first major release game so I could use all the help I can get ill link the Scratch project as well for the UI but I’m also figuring out a name for the game on Roblox I’m thinking of some right now but unsure about them at the same time The Scratch Game for the Train Sim’s UI Tester Feel free to Remix the project and edit it and fix anything that seems wrong this is the best I could do since I first started it.

As a quick teaser, the first FREE map for the game is going to be based in my hometown of Norwalk, Iowa, and Des Moines, IA, with the following railroads that are also FREE: Union Pacific Railroad, Iowa Innerstate Railroad, and the Iowa Central Railroad. don’t know what other ones to add but there is supposed to be foreign power as Canadian National and BNSF run through Downtown Des Moines every now and then
