Hi,

I wrote an Apex triggers which update some custom field of Contacts. When I am trying to install the trigger in my sf account, it tries to create the Cutom fields on contact and if these fields are already present an error message pop-ups and installtion fails.

Could someone please suggest how I can by pass the creation of the custom fields on contact i.e. if fields are already present then do not create the same fields again during installation of package and also do not delete the fields during uninstallation of the package.

Please help me out. Thanks in advance for your reply.
