How new are you D? If you don't know how magick works, what magick is, and 'the basics', no spell will work for you.
Also, what kind of spell were you hoping for? Protection, healing, curse, transformation? Some spells don't work because of the nature of magick, other spells require a deeper understand. Look up circle casting and work your way up to spells. Spell casting is, like, step 5 in the learning process, if you skip the previous steps, it will not work.
