What does C-h v org-export-use-babel RET say?

If the result is not `t' that is the problem, and somewhere in your setup 
you have set that variable (or its predecessor org-export-babel-evaluate) 
to nil or something other than `t'.

If this is the problem, set org-export-use-babel to `t'. You might 
also note the advice in the docstring:

"Users who wish to avoid evaluating code on export should use the header
argument ‘:eval never-export’."

HTH,
