Hi,Everytime I set up the snipe price,but it would change to "your snipe is NOT ative" status after a while.I have to set it ative again and again,now I have missed many auctions. What happened?

You did not provide the item number to check, but it sounds like you set a Group with limit "1" item to win, so once the sniper met the goal you set, then it cancelled the rest.
You should either set another limit or don't use Groups.

You can find more information about Groups in the following FAQ section:

YesI set some group,but did not set limit "1" item to win,please see the attachment.

Now I provide two items of I missed before:112385892611 & 112385915837.
Please check it,thank you.

I don't see the Group setting, but it probably has "1" in it. Please check under "My Groups" tab.

It seems to me that the problem's been solved,thank you for your help.
