If you are prepared to post the transaction's ID here we could provide more help. To get it click electrum's history tab, then right click the top transaction and select details from the list that appears. A new window should open with the transaction ID in a text box at the top. Copy that and post it here.
If you don't want to post it here search for it on this page.
