Is there any way I can insert the company name of a linkedin user? Thanks.
Hi, and welcome to the forum! 
Unfortunately, LinkedIn doesn't provide a well defined answer to what someone's company is.
The most straightforward thing would be the users "headline", unfortunately that usually contains other content in addition to the company and it may not even include their company at all!
On the person's profile page you'll have work history. However, they may have multiple ongoing active work history items and the primary company you looking for might not be the top one in the list.
Ok, thank you for the reply. In this case, is it possible to make a manual entry?
It sounds like you would like a form field in your snippet where you can enter the company name.
We have great support for that and you can learn more here:
You can combine a {formtext} with a {linkedin-headline} command to automatically populate the text field with the headline and then you can edit it manually. You can learn more about the LinkedIn command pack here:
