Maybe its the wrong file format to be allowed maximum attachment ize is 1024 Kb.
What i sometimes do when its the wrong fileformat is take a screenshot of the schema to make it jpg.
Also you should have a look at these 2 books i uploaded .
http://rapidshare.com/files/110320785/Switching_Power_Supply_Design_2ed..pdf
http://rapidshare.com/files/110114719/BROWN__M.__1990_._Practical_Switching_Power_Supply_Design.pdf
They give a step by step aproach on how to calculate and make inductors and transformers for most purposes .

Goodluck Walkura
