Question on ln in a for/next loop

[SMcNeill]

Pasted as is, it works in the IDE for me.  Best way to get something like this fully identified and looked into, is to zip up the file and resources (if necessary) and share them on the forums here so we can dig into it deeper. 

There's not a lot of things which generate that type of error message for us, so I'm thinking a variable mismatch is coming into play somewhere/somehow with things, but it's hard to prove/test without having the actual code in front of you.
