[Asterisk-Users] Loops and Variables

[Doug Lytle]

I have the following in my dialplan, counts the number of loops and when 
it hits greater then 5, exit.  It works, but errors initially with,

"syntax error, unexpected TOK_PLUS, expecting TOK_MINUS or TOK_LP or 
tolken; Input: +1".

Could somebody tell me why?

Thanks:
