The constructor should be payable if you send value - solidity

Question

I'm running this code on remix IDE. Everything is working fine except the function transfertocontracts(uint amount) public. I'm trying to transfer some ethers for e.g. 10 to my contract and then later using this function function Transfer_Contract_Amount() public I will transfer all the amount of contract to specific address.
The problem is that when I run function transfertocontracts(uint amount) public I'm getting this Error:
Note: The constructor should be payable if you send value. debug the transaction to get more information.
contract SLA {
address seller;
event DepositFunds(address from, uint amount);
constructor() payable public {
seller = msg.sender;
}
function transfertocontracts(uint amount) public {
address(this).transfer(amount);
}
function seePerson_Amount() public view returns(uint) {
return seller.balance;
}
function seeContract_Amount() public view returns(uint) {
return address(this).balance;
}
function Transfer_Contract_Amount() public {
seller.transfer(address(this).balance);
}
}

Answer 1

You can send ether only by using the value attribute which you can set while interacting with the Smart Contract. Below is the working code
pragma solidity >=0.4.22 <0.6.0;
contract SLA{
address payable seller;
event DepositFunds(address from, uint amount);
constructor() payable public {
seller = msg.sender;
}
function transfertocontracts(uint amount) payable public{
}
function seePerson_Amount() public view returns(uint){
return seller.balance;
}
function seeContract_Amount() public view returns(uint){
return address(this).balance;
}
function Transfer_Contract_Amount() payable public{
seller.transfer(address(this).balance);
}
}
To check you can run it on remix and on the run tab on the left side you can putt the value of ether to send and run the transfertocontracts function further to store the value its a good idea to use the msg.value.
