Thanks alot sir

I would have suggested the same two web-pages Mario did.  For another nice one on binary logistic regression, see Module 4 on the page linked below. 

I've also attached some notes I wrote back in 2003 when trying to explain to a colleague how the odds ratios worked in a multinomial logistic regression model where the outcome variable had 3 levels.  Perhaps you will find it useful. 

HTH.

If you want a good book with complete easily explaned theory and well discussed examples to each chapter than read "Discovering Statistics Using SPSS" by Andy Field. It's primarly written for non-statisticians but also statisticians get a lot of useful information.

Best regards, Antonia

Thanks alot antonia...

I agree with Antonia Griesbacher's response.  I have used Field's book both as a text in my research seminar classes and as a resource for my own research.  His book is well-written, and his chapter on logistic regression covers both binary and multinomial regression with good explanations for how to interpret the odds ratios.
