Trying to deploy development from my sandbox using change sets. Whilst custom fields, tabs etc come across fine, the triggers are failing with the following error:

Code Coverage Failure Your organization's code coverage is 0%. You need at least 75% coverage to complete this deployment. Also, the following triggers have 0% code coverage. Each trigger must have at least 1% code coverage.

This means nothing to me and I'm just getting more confused looking through the help documents. I don't really do code and I don't know where to start. Any help would be very much appreciated
