trade in button does not work

[Allen4]

I try to use my trade in code in the cart page, after I clicking 'apply to cart', there is no reaction for the page. The button just turns to grey but no other reaction. The samsung assistant told me it may be because I have tried too many times, what should I do now?

You may have to wait until the next day possibly.
