Please, I don´t know why my Electrum Bitcoin Wallet tell me: "Invalid Fee"...
Can some body tell me how I can do??
I cheked my fee and is good.
Thanks
What value are you using for the Fee amount? You should make sure this is a valid value and that you have enough for the amount of the transaction + fee. For ease of use, I'd recommend you try out the Dynamic Fee option ( Preferences -> Fees -> Use dynamic fees ). This lets you use a slider to specify your fee based on how fast you wish the transaction to confirm. Its a bit simpler to use and pretty convenient.
