Campaign Email Survey results

Hello,

There is couple of issues involved in this post . Please help to fix this issue.

I have created a survey using transaction code CRM_SURVEY_SUITE and included in this survey in Mail form and send this email to customers/prospects with the  help of campaign. This survey is public enabled. 

When customer open the survey in email ,survey opened successfully but when saved the survey ,error “The values cound not be analyzed. ”

When I try the same thing in GUI , I’m getting message "The Values Were Saved Successfully" but

When I choose Evaluation in the transaction there is  “No data is available for evaluation” message is coming .

Please guide me to fix it.

Thanks ,

Naveen
