How to content lock a button?

Hey folks.

I'm using PPS and have a question. I'm new to this again and have forgotten, is there any chance for me to get people to see it like this:

They get their product/thing by filling in their email. [YOUR EMAIL] [SUBMIT BUTTON] How do i make people available to write in their mail in the little box but when trying to submit they have to complete the survey?
Is this through content-locking and how?

And which PPS is best out there with honest opinions and no advertising. I have regged to purebits but I'm not sure, I saw something called Roaringcash that seemed 10x more professional but no reviews available.
I thank you for any info provided! Nvm my shitty English

That Is content locking. A lot of CPA networks have a content lock feature, and they will have guides there.

For offers I use CPA Lead (I think they have content locking as well), and for the content locking Itself I use Mighty Content Locker. You don't need to buy MCL, because I'm pretty sure CPALead has their own content locker.

I just use MCL to mix and match offers between different networks.
