This sounds to me like there was an error when trying to estimate the gas it takes to deploy the contract.
You can try to deploy it on test net first to see if it works.

I did it in the test net
0x1b97f4b1ba923d1A98BC359f080180fbCf7615A4
If you can, copy this token contract and create the contract
this is on main net: https://bscscan.com/address/0x1b97f4b1ba923d1A98BC359f080180fbCf7615A4#code

I copied the contract from this token
What is the problem? If the contract has been deployed to the mainnet, then there are no problems in it.
You have this error because you are trying to deploy to testnet contract for the mainnet. For example:
IUniswapV2Router02 _uniswapV2Router = IUniswapV2Router02(0x05fF2B0DB69458A0750badebc4f9e13aDd608C7F);
You can’t use mainnet addresses on testnet

Thank you very much 
I made the contract 
Now if the purchase is made
Zero tokens are sent
How can I disable this feature?
I guess that you put a parameter and click on function name to make a blockchain transaction with that function and parameters.

Transaction Hash: (set LiquidityFeePercent)
0xe51ea4ae89bca50baa4f2a26ba77d9d0e0e0f141991095e1f8357063bd91a3d1
This the transaction sample is registered. Can you get its parameter?
parameter = 000000000000000000000000000000000000000000000000000000000000000c

transact to BabyADA.setLiquidityFeePercent errored: Error encoding arguments: Error: invalid BigNumber string (argument=“value”, value=“000000000000000000000000000000000000000000000000000000000000000c”, code=INVALID_ARGUMENT, version=bignumber/5.4.1)
The first code worked. I extracted the second code myself
Gave an error

You can also try to execute directly from bscscan that function, from write contract tab.
Maybe you have to put only 12 and not that big string.

I entered several types of parameters.It was done but it did not work
Currently, if someone makes a purchase, they will be given zero number
We need to understand how it is activated.
This contract is very smart 
Blocks robots,I hope someone can decrypt…
Hey @Diamond
We are ready to help you with solving problems, but we cannot make a smart contract for you or study its work and then tell its operating principle. It is a long and hard work that requires attention and time. You need to do your own research 
We are ready to help, but we need a detailed description of the problem and information about the attempts made 
Please open a new thread for your question, closing this thread as it’s a separate issue.
Let’s keep 1 thread = 1 issue so its easy to find solutions for future users
