In our Marketo Webinar Registration Forms we're asking for Country (it's a required field).
It's stored in English Language in our Marketo Database.
For e.g. "United States" or "Germany"
But if I check the registratin list in GoToWebinar this country appears each time with value "Others".
Does anyone knows how to fix?
Sounds like the mapping values are different. For example, you may store country value as "United States" or "Germany", but GTW stores them as "USA" and "DEU". Have you checked with GTW?
You need to contact them. Or you you could go out to one of their own registration forms and look at the HTML code.
