Ensure that your amount being sent is lower/equal to the amount available in your account. Assuming that you are talking about blockchain.info wallet, they do not take any fees. You can set a 0BTC fee if you want to but you would have to wait a longer time for it to confirm. Additionally, I would recommend against using blockchain.info due to their frequent glitches.
