As loki pointed out, mIRC does not recognize the alias add.pts due to a syntax error.
Since you obviously copied this code from youtube or something, you're probably going to need a lot more knowledge in the language before you attempt to create your own bot. I suggest reading the help files before trying on any of the advanced features of the language.

The answer to your situation however is to change
alias -1 add.pts {
alias add.pts {
