help me resset my ipad passcode

If you've forgotten the passcode then you will need to connect the iPad to the computer that you normally sync to and you should then be able to reset the iPad and re-sync your content to it (http://support.apple.com/kb/HT1212) - you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808

If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present.
