Stack too deep in solidity

Solidity Programming
#2

Hey @iammoud2

In your code there is a lot of global variables, most likely this was a problem when you tryed to add a new one. There is a limit of 16 or 18 variables.

So, how to beat this limit?

You can use functions _getValue instead of creating global variables. And it’s already used in the provided code:

For example:

Instead of creating variable :

address private _devWalletAddress = 0x000000000000000000000000000000000000dEaD;   //Burn

You can add this variable to:

    function _getTValues(uint256 tAmount) private view returns (uint256, uint256, uint256, uint256) {
        uint256 tFee = calculateTaxFee(tAmount);
        uint256 tLiquidity = calculateLiquidityFee(tAmount);
        uint256 tCharity = calculateCharityFee(tAmount);
        uint256 tTransferAmount = tAmount.sub(tFee).sub(tLiquidity).sub(tCharity);
        address private _devWalletAddress = 0x000000000000000000000000000000000000dEaD;  
        return (tTransferAmount, tFee, tLiquidity, tCharity, _devWalletAddress);
    }

am i doing something wrong?

function _getTValues(uint256 tAmount) private view returns (uint256, uint256, uint256, uint256) {
        uint256 tFee = calculateTaxFee(tAmount);
        uint256 tLiquidity = calculateLiquidityFee(tAmount);
        uint256 tCharity = calculateCharityFee(tAmount);
        uint256 tTransferAmount = tAmount.sub(tFee).sub(tLiquidity).sub(tCharity);
        address private _devWalletAddress = 0xE8A4eF706d4e57210cB6CE5781C052Cc0331B616;  
        return (tTransferAmount, tFee, tLiquidity, tCharity, _devWalletAddress);
    }Preformatted text

is said: Expected ‘;’ but got ‘private’ where am i missing/ having typo?

Oh, sorry my bad. It was just an exapmle. Use it without private

address _devWalletAddress = 0xE8A4eF706d4e57210cB6CE5781C052Cc0331B616;
#7

i dont know how it may sound, but can you plz complete the code?

#8

What do you mean?
To add the function of receiving the address or the whole smart contract?

#9

To add the function of receiving the address.

so, i need to set the 4% tax exact same way as tha charity wallet is added?

#10

I just want to clarify. Does the code from the github compile without problems?

#11

yes it does…but i want to add another wallet(dev) as mentioned

#12

The problem is I can’t deploy it to the local testnet because of routers in the smartcontract… and test it. So, I need your help.

Try to add _devAddress 

address private _charityWalletAddress = 0x000000000000000000000000000000000000dEaD;   //Burn
address private _devAddress = 0x000000000000000000000000000000000000dEaD;   //Burn

And the question: which function you tryied to change for making extra fee?

#13

let me change the router address for testnet
