Solidity Tutorial: Sending Ether to a smart contract (function payable keyword) 

yeah silly me haha

Set the mapping outside of the function and not within the function. mapping(address => uint) public balances; function invest() external payable{ //track address to amount of ether if(msg.value < 1 ether){ revert(); } balances[msg.sender] += msg.value; } function balanceOf() external view returns(uint){ return address(this).balance; }

I am not sure to understand your question? Could you reformulate?

@@EatTheBlocks hi sir, what I mean sir, if I have the smart contract already created still we can integrate the additional contract that you make or this is part of the erc20 functions

@@EatTheBlocks how can I contact you directly sir thank you

@@vedxtoken699 I am very sorry but I still dont understand the question :( If you want to explain your problem with more details, you can register on the forum of the channel, forum.eattheblocks.com

@@vedxtoken699 I sent you a link to the forum of eattheblocks

you need to call these functions on the ERC20 token: 1 - approve() 2 - transfer()

@@EatTheBlocks Thanks! where do I do this? How would I update this smart contract?

@@EatTheBlocks Do I input the private key into MEW wallet and then change/modify the code from there? Or do I need to run it on Solidity? If you have a video or instructions on how I can do this I will donate some Ether to you, I dont have much but will send what I can. Thanks.

@@MrHanSoL0 I am not sure what you are trying to do exactly. If you want to send an ERC20 token from an address to another one, you simply use a Wallet that can send ERC20 tokens, like Metamask. If you use a smart contract to send ERC20 to another smart contract, the first smart contract needs to have a function to send the tokens, otherwise there are stuck inside the contract. If you dont have a UI for this smart contract you can use Etherscan. You search the address of the contract, and on the page of the contract they have a read and write tab where you can execute the function of the smart contract.

@@EatTheBlocks ahh okay, that helps! Thank you, will let you know if successful, thx again.

Hi Robert did you manage to get your coins? Having the same problem here...

@@Dave-pz2pz nope, it is lost forever

@@kobki66 Thanks for letting me know, guess ill have to open a bottle of whisky and try to feel less stupid;( The scammer does have the balls to keep interacting... Anyway wish you a good christmass and lets hope crypto will payout in the end..

@@Dave-pz2pz Thank You Dave. I wish you Merry Christmas too! did you tried flash loan code?

@@kobki66 Never heard of it, thanks for the advice! will try and look..

haha thanks Astra :)
