Confusing.. Registration gets you nothing.. then you end up paying then you can do something. Why Register if you cannot do anything with the form... does not make sense.

Obviously, the sales portion of the Web site needs clarifying, but customer support could not have been more generous and quick in solving my misunderstanding. Wish all companies did as fine a job.

Slick tool. Nice editing capabilities. Some of the menus are confusing - for example: finding where to update an existing link to fill document is challenging.

I cannot find enough praise..
I cannot find enough praise for the support team at PDFfiller. That the products are exceptional goes without saying, but even the best product can fail without a solid customer service/ support team. Each time I have contacted PDFfiller I have received a prompt response outlining viable solutions and knowledgeable answers. With PDFfiller you may sign up for the product, but you will stay for the unparalleled support.

5 Answers. Changing the order in the first double sum is manageable. We could therefore use it as some kind of prototype. We transform the second double sum, so that the index range is similar to the first one.
Can you split up a summation?
