Hello, I have started scripting recently and I have encountered a problem with a login system. Here are error messages:
D:\Documents and Settings\Administrator\Desktop\Sa-Mp Server\rD\pawno\Login.pwn(41) : error 001: expected token: "-string end-", but found "-identifier-"
D:\Documents and Settings\Administrator\Desktop\Sa-Mp Server\rD\pawno\Login.pwn(41) : warning 215: expression has no effect
D:\Documents and Settings\Administrator\Desktop\Sa-Mp Server\rD\pawno\Login.pwn(41) : error 001: expected token: ";", but found ")"
D:\Documents and Settings\Administrator\Desktop\Sa-Mp Server\rD\pawno\Login.pwn(41) : error 029: invalid expression, assumed zero
D:\Documents and Settings\Administrator\Desktop\Sa-Mp Server\rD\pawno\Login.pwn(41) : fatal error 107: too many error messages on one line
Here is 41 line:
format(string,sizeof(string),PATH,playername);
What should I do?
