How to pass a variable from one component to another?

Question

1C-Bitrix

Good afternoon, I've been scratching my head for several weeks now...
There is a component with several elements in it, each element has a link form, I want the variable from the first component to be passed to the link form. Let's say this is the name of the element. I achieved this through a global variable, but only the name of the first element is passed to the contact form. And I need the forms to have an appropriate name (like the first elements)
