I don't have much in there but what I do have I want back! I used an address from Coinbase, then transferred or so I thought I did, bitcoin. Coinbase doesn't have it, and nor does Electrum. I have a "0" balance. No one knows anything. Highly frustrating. I'm a student and need those coins to help me get through the rest of my tuition expenses!
No one can help you unless you provide us with the transaction ID ? If you do not know this stuff, the send us the sending address from electrum and the receiving address from coinbase. It may be possible that your transaction is still unconfirmed because of low transaction fee.
