I install Toolset Forms Commerce but i struggle to work with it.
I have already problems to activate the Plugin, i can't find this menu i send you at the screenshot.
Is there a learn video about the plugin as well?
Can I suggest that you review this lesson about using Forms Commerce, and if you still have problems getting it to work once you have read through that, please let us know and we will try to help.
It shows the initial, form building wizard screen. Once you've completed the wizard and saved the form, you'll see the payment settings at the bottom, of the form editing screen.
( example screenshot attached )
The latest screenshot suggests that you're still on the form-building wizard.
Can you please complete this wizard first? Once the normal form editor screen loads, you'll see the payment settings at the bottom.
(as can be seen in the screenshot from my last message)
