Can tokens in LR be nested?

I'm trying to figure out a way to optionally have a comma.

If I have a Title, or a Caption, then I want a comma before the Copyright info, but if both Title & Caption are empty then no comma.
Any insight would be appreciated.

Thanks,
:-)

Look at the LUA programming section of the token docs for conditionals

Re: Can tokens in LR be nested?

I did something similar to what you want to do using this code in the caption tokens field:

{Title} {LUA=if Title ~= "" and Caption ~=  "" then return " - " end} {Caption}

It puts a "-" between both the title and caption if the caption exist.
