What do you think the above paste is doing? Did you try it outsider loop?

Where is Print_Message from?

> print(i) sheet", Trial.Arms, print(i).Arms, "Trial level sheet",

The message comes usually from syntacticaly invalid commands. Missing commas or something like that.

What do you want actually to achieve?
