Guest Invoice Link-link text in email template

I created an email template for clients and used the template tags in the body for relevant info. The invoice guest url tag creates a long link in the email body.
I tried to use:
a href=“http://{{{invoice_guest_url}}}”>invoice link<

(left off closing tags so it wasn’t displayed as a link)

but that doesn’t work (didn’t expect it to). Any suggestions for the web challenged?

Thanks in advance

Here is how I use the link in my email template.

a href="{{{invoice_guest_url}}}">Click Here<

That worked! Thanks for your help.
