I’m trying to make a custom hotbar but it seems like once i click 3 numbers it stops working

I’ve trying fixing it but it doesn’t seem to work.

i have made a hotbar system using the roblox official default hotbar module and i think someone published in roblox here it is and you can do manu stuff with it
https://www.roblox.com/library/276256649/ROBLOX-Default-Backpack-Gui?Category=Models&SortType=Relevance&SortAggregation=AllTime&SearchKeyword=default+roblox+backpack&CreatorId=0&Page=1&Position=1&SearchId=caa5e186-ed45-46a8-8fea-434499e093ef

here is an example of what i did with that module
