1. you need to combine all solidity file into only 1 file
2. make sure to choose the correct solidity version when did you deploy

I change many ways but still the same error
1. Change contract name
2. Change version
3. Change gas type
4. Change source code

reissuable is not fixed Total Supply? i do not understand what you mean? total supply is fixed and can not create more

If you created the token via tomoissuer, then the contract name is MyTRC21Mintable for `Reissuable ` and MyTRC21 for `Non-reissueable`
Edit: If this is your [token](https://scan.tomochain.com/address/0x5080781e91237b6d7f026d5306b7233e26cd6c16), then the contract name is MyTRC21, compiler version should be 0.4.24, optimization: yes

Go to the token detail page [example](https://issuer.tomochain.com/token/0x381b31409e4d220919b2cff012ed94d70135a59e)(might have to log in). Look for the `view token info` option
