Hello, again, all! When I posted my original message last night, I had not downloaded the trial. I did this morning and I must say that the software is a snap to use.
I first created a subdomain called "forms" so my root directory would not get cluttered. Then I created a test database, a test form (called "test1"), a test Admin Module, and published the test. Then I went into my cpanel >>File Manager>>Forms>>test1_files and found, among others, config.js and config2.js - I highlighted each in turn and clicked on 'Edit' and was able to see the code.
config2.js was the file I asked about and, sure enough, the settings can be edited within one's cpanel. That is especially important because, for a reason I cannot explain, when I was on Step 4 (Admin Module) within the Seagreen environment on my desktop, as I was creating the test form, there was no right scroll bar but the box to enter a re-direct url was "below the fold". I could neither see it nor find a way to get to it. But 'thanksURL' : "", is one of the pieces of code within config2.js; so it is easy enough to insert the re-direct url between the quotation marks:
'thanksURL' : "http://www.mydomain.com/thanks.html", for example.
But it would be nice to know of to cure that apparent bug in the software.
All in all, though, I think Seagreen is a real nice addition. I am currently paying $49 semi-annually for an online service. All I get for that is to be able to create forms online, get the code, receive email notifications, and have the ability to export data to a csv file. But the code comes un-formatted ("so you have complete flexibility to create any style you want") and if I cancel the subscription, I lose access to my forms. Let me think, $98 per year with fewer features or a one-time fee of $149, free upgrades, and complete control of my forms. Gee...
