Phil thats the wrong form.
For the new S7's you have ordered you need to fill out the "Miner Order" online form, not the "Miner Config"
You fill out the order but don't pay it. When you fill out the order it asks for your config.
After you select Ant S7 and then "Select this type" Miner Price/Each you should see a screen like this:
That's why we are doing an order for each miner, because each miner will have slightly different configs for some people (different worker names for mine)
You can see he says it here:
philipma1957 ,biffa, mswells, junky998, invader, you can send me your mining setting now, you can send it by placing a order on our system, fill the mining setting and leave it as unpaid and i will confirm it manually
BTW mine are not mining either
