Help me beat my friend

United States

#1 May 10, 2013
Hey everyone, kinda new here. My friend gave this challenge on facebook, and based on what he's given me, I've come up empty handed.

Here's what he's got:

PerGromark Forest


Periodic Gromark, Forest maybe the primer? Not sure. 634215 is a lot like enigma, but may be there just to throw people off (also why forest is there, may not even be periodic, I thought it was running key.)

Anyone have any suggestions?

The cipher is a Periodic Gromark though it seems to contain a few errors. I think the plaintext reads:

"If you can read this you are my hero".
