Type Mismatch in URL link

I am creating an email in LS with a list of URL’s. I keep getting a type mismatch when I run the agent. Am I missing something obvious with my code?

Any help would be appreciated!! This is what I am setting my URL with:

Set URL = keybodyURL.values(0) + doc.Contact_Plyr_Nbr(0) + “?opendocument”

keybodyURL is a keywords document that contains http://server/database/

Subject: Type Mismatch in URL link

This may not be the problem, but if you use ampersand & instead of plus sign, Notes will convert everything into a string without needing any formatting functions (such as Cstr).

I say this because I am guessing that Contact_Plyr_Nbr is a number field, and the others are text.
