problems regarding varpart function in r

Rajendra Mohan panda 
Dear members

I get immense help from this forum. Therefore I put my problems to this
forum without hesitation. I also thank you all for quick and valuable
responses. This time I face problems with *varpart function* and *forward
selection* while using vegan. I herewith attach my codes I have run in a
separate file so also a sample data structure for your kind reference. Look
forward to your valuable guidance and advice.

I have arranged the whole data into to tables in name SA (with sites and
species) and SAE containing only environmental variables (here I have
considered three).

I will be grateful for your help and response.

With best Regards
