Called function conditional testing (if) of form variables problem

[Eduardo Biano]

Hi,

I have a problem making conditional testing (if) of a
form variable "ans01"(refer generated error). When the
form variable is tested (if) by a called function
(foo) the value of "ans01" is not properly
represented.  


def foo(request):
    ans01 = request.get_form_var("ans01") 
    if ans01 == 4:
        ans_1 = 1
        return ans_1  

The browser returns a blank screen or ans_1 is blank.
I tried to "return ans01" and the browser returned the
number 4. I am quiet sure of the above code and
searched python resources but found no solution.
Please help. Thank you in advance.
