Hello there,

I had a problem with multiple links to.

It wont work also with the solution linked above, because the function works always with the same tag ("hyper"). In case of an iteration we have only one tag, that simply gets a new url each iteration. Different hyperlinks added in this way receive this one identical tag as well as the last url from a list.

The problem was already solved by martineau from stak overflow. So based on the solution I made a small function that works fine for me.

I hope this information will help somebody.
