I have created a payment link for a t shirt with multiple sizes but It wont create a cart

[CHP]

We are selling cast t-shirts for a play and we are sending out a payment link url, but it only allows people to select 1 item size and then check out.  We have families that want to order more that 1 shirt.  is there a better way to do this?

Here is a link to the t-shirt sales: https://checkout.square.site/buy/RTPBH3KFBTGLJF4LDP4QSXLV

Any help will be appreciated for the future

Hi Chp,

I believe the way the link works is by design.   Square Online Checkout Links only allow a buy now option as you are doing an Express Checkout - there's no Add to Cart or continue shopping option.
