undeclared identifier, got no experience

[m20072]

Hey, before I post my problem I must say I have almost no experience at all with c++ tho somehow I managed to almost completely update something I really need to get to work.. i got these 3 errors and 5 warnings:

Error	2	error C2065: 'pfDisconnect' : undeclared identifier	c:\meh\serverplugin_empty.cpp	152	1	tf2lss

Sorry I cant post the whole code its too long
I will appreciate it a lot of someone could help me fix it up asap, thanks!

[gelatine]

it would help if you also showed us your code ? ;)

It doesn't let me to put it in a code format and also had to delete couple of includes to be able to submit a reply lol

I don't see that you have declared pfDisconnect anywhere.

[m20072]

That's good that you found the solution but what should I do about that? I've said I have no experience ;p please reply to me, thanks!

[krutuk]

Interesting... You said that you haven't any experiance. But program looks not very easy. Did you write it by yourself or just copy from somewhere and than chenged?

[m20072]

Of course its a copy :P, what I updated was couple of header files that I downloaded from a site ;p

[krutuk]

Honestly, I am beginer too and I want to give an advise. Do simpler programs, it will be easier and more useful. But, it's just advice :-)
