Thanks for the heads up Cyclic.

SyZy, read through the tutorial carefully and take it step by step.

These tutorials are compiled by experts in their own time and if followed correctly will solve most problems.

There is nothing more frustrating than to post a link that you know for a fact hasn't been read. How do we know you might ask. We know because people come back with questions such as yours, which wouldn't need to be asked had you checked the link I gave you.

I repeat, check the tutorial. Everything you need to know is in there.
