please i need help(solidity)

I copied the smart contract [https://snowtrace.io/token/0x26deBD39D5eD069770406FCa10A0E4f8d2c743eB/contract/code?chainid=43114] completely, completely, clean, there are no errors or anything (I mean the syntax), but it still doesn't work. Does anyone know why? I have 1 thought why it doesn't work. I think that for some reason snowtrace.io/ doesn't show me the supply of this smart contract, which means I didn't copy it.
P.S. I have all the imports and all the files as in that smart contract
All my folder names are also the same, which means there shouldn't be any problems with importing
