I want help with gui

Hello Catalin, are you Romanian, your name is Romanian? If so than please subscribe to my channel as I will make a video tutorial just for you. If you don't understand Romanian than here is what you have to do:

1. Open GUI editor and click "Inventory" under the "Add new inventory" Tab on the right
2. Choose a name for your Inventory (This will not display in the game, it's just a matter of organisation)
3. Choose the number of slots and MAKE SURE " Drop items fron inventory when GUI is closed " IS NOT CHECKED!
4. Select the GUI Type "GUI with slots" from the drop-down menu under "GUI Properties" on the left
5. Add slots by clicking " Input slot" under "Add new slot" on the right
6. After you are done click "Save changes" and close the GUI Editor
7. To open the GUI you need to make a procedure with "Open GUI for provided player" block you can drag from "Player management"
8. Add the procedure you created to the item by selecting it from the drop-down menu under "When right clicked in air(player loc.)" and "When right clicked on block(hand loc.)"

Did you succeed making the GUI?
