What do you mean exactly by "the marketplace"? I'm assuming you mean an e-commerce plugin but which one?

I just saw your other messages so I guess you are using Community Store.

You have to make sure the Square Payment processor is enabled. When you set it up in the dashboard (as explained here:https://www.concrete5.org/community/forums/installation/community-st... there is an option to make sure it is enabled.

And of course, your products also should be enabled.

If both are enabled and you still don't see a button, you might have something on your site interfering with it.

If it's a live site please share the address so we can have a look.

Yes, community store. I have filled in those details, but still see no button to buy.

The page is here:http://www.widp.org/index.php/test...

When you added the product block to the page, did you check the box that says "Display Add To Cart Button" ?

I did. Attached.

When I inspect the source, I don't see an attempt to put the button there.

ok, so the last thing I can think of is to go to dashboard/store/settings and under cart & checkout and make sure cart & checkout are enabled

I was checking in payments. I missed that option. ARGH!

Thank you so much for helping an idiot.

lots of options, easy to overlook them.
