Hiya, sorry you are having trouble getting your forms to work.
I see you mentioned you read several threads in these forums. That is a great starting place! Have you also seen our Support Guides? This Support Guide is the first port of call to debug any forms issues.
If you have already read our guides and you are still having problems, please provide more information such as what you have already tried, a link to your live form, your form name as it exists in the UI, and any additional details you think will be beneficial for us to debug this further.
