Forums mIRC Help HELP please on this code..

i post in very top of the remote 1-23 lines, the -->> " while %a <= %b { " is in Line 15 but still not working, said

* Break: command halted (line 15, remote.ini)
and
* /msg: insufficient parameters

i also transfer the " while %a <= %b {" to Line 19 but still won't work.. i noticed that this "while %a <= %b { " is the problem.. this is weird huh.-.-
