Hello! first post


I sent coins from localbtc to electrum. the coins showed up fine in electrum. I then sent the coins to..another address..and electrum said they sent. I saw the transaction in the history of electrum and closed electrum and waited 1 hour as i normally do. I then checked the address i sent to only to not see the coins. I open electrum and check history but do not see the sending transaction i did before. I see the coins in my wallet again. I figured i must have not sent it correct and try to send them again and get this error: "error u message u18 bad-txns-input-spent-ucode 26"

30 hours later the coins are still showing in my electrum wallet, not showing the sent transaction and i am unable to resend the coins because of the error.
