Lesson 4, withdrawal

[czilauto0r1]

Hi, just started my adventure with that course love it, I had some problems before, everything solved but this time need some help.
So, no errors while compile, if I switch account which is no owner I'm getting message Sender is not owner! so that means it works but when I change back on owner account and click withdraw I'm getting gas estimation failed gas required exceeds allowance (29999972) and I can't withdraw. Here is my code sorry for that mess with comments but its helpful for me. (and english its my second language)

Here is my code: https://gist.github.com/czilauto0r1/055d4c8cfe1efa9080ace73da1d00162

[czilauto0r1]

nope, still same. I even start JS course to have some maybe more ideas for now I don't know what's wrong.
////// update
I change that like you said it didnt work but when I reload page its working now. Thank you.

I'm having the same problem...I've been at it for a couple hours now but still get the same error. I've triple checked the code and have back tracked a few times in the video...I could just copy and paste the code that Patrick has in his repo but that wouldn't be very beneficial...Did you ever figure this out ? I included the payable button (which isn't included in this part of the course on Patricks code)...Same error. I've switched around the modifier to be above the withdraw function (though the underscore in the modifier should provide that utility)...Same error. Any advice??

So I have decided to try to use other peoples code that were able to withdraw successfully...I am still getting the same error message

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
err: insufficient funds for gas * price + value: address 0x089d32a95b5Bb0732Ea154291aeA4fCe8e8b34ba have 40235652391756436 want 50000000000000000 (supplied gas 15010499)

I know now that it wasn't anything wrong in my code, but this still has me stumped...I know it says it is a gas issue but I had the amount in my wallet and deployed multiple contracts trying to figure this out but the problem is still there.

@czilauto0r1 Hey so i was actually able to get this to withdraw successfully. What I changed to make this happen was adding this to the top of my code.(which in that part of the course wasn't in the code but maybe the program requires it now or something changed)

import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

Is your code almost exactly like: https://github.com/PatrickAlphaC/fund-me-fcc

Try to see what is different.

I'm sure the solution is something very simple, but my brain isn't processing it for some reason(My code is in the discussion above)...Any advice on this would be greatly appreciated...Thank you for the time you took to make this course... I've already learned so much ! Have a blessed day.
