How do I get constraints to work?

Hi!

I am trying to get constraints to work on several boxes. I want each box to have a split between the left and the right. For “Product Name” and the cost, I want “Product Name” on the left and cost pushed to the right. Same thing for “Shipping” and “Total”.

I have each of them in frames. I set the constraints parameters, but nothing happens. I have tried everything I think of, but I’m not sure how to fix it.

I am attaching a screenshot to illustrate the elements I am trying to apply constraints to.

Could someone please shed some light on it?
