Well, I see that you are frustrated but you might want to consider blowing off your steam before posting.
Are other snippets working on the site? Are you by chance pasting eForm into the Rich Text editor? Have you got a working copy of MODx with the default dataset installed? Are its snippets working on your server?
The reason I asked what you wanted to achieve with eForm is because there is not any reason to put an [[eForm]] call on the page you send them to after that have completed the form. Any eform call REQUIRES the following parameters (per the documentation which is located in /assets/snippets/eform/docs/)
formid,
tpl and
report so if you have a call without them it won’t do anything.
So at a minimum you call should have the following:
[!eForm? &formid=`feedbackForm`&tpl=`eFeedBackForm` &report=`eFeedbackReport`!]
The parameter values should be whatever is in your template.
If you are just wanting to show your respondents a thank you page, create the thank you page and put the id in the gotoid=`n` where n is the id of the thank you document.
Otherwise share with us what kind of form, contact, upload, request, subscription etc. and paste your form template as well.
Cheers,
Jay
