To get rid of warning 217, you must indentate your code, like this:

Код:

public OnFilterScriptInit()
{
  code();
}

not like

Код:

public OnFilterScriptInit()
{
code();
}

Indentation means when there is an opening bracket, next line must move on by 4 spaces (in PAWNcc default is 8, yet it is defined to 4 in a_samp.inc). You can generate that by pressing TAB.

You get the errors at line 121 because you don't close OnPlayerSelectedMenuRow properly, you do this:

Код:

public OnPlayerSelectedMenuRow(playerid, row)
{
new Menu:CurrentMenu = GetPlayerMenu(playerid);
if(CurrentMenu == shop)
{
  switch(row)
  {
    // cases here
    }
    return 1;
}

Indentation plays a big role, so you could see what is wrong.
You miss a } (closing bracket).

Код:

public OnPlayerSelectedMenuRow(playerid, row)
{
  new Menu:CurrentMenu = GetPlayerMenu(playerid);
  if(CurrentMenu == shop)
  {
    switch(row)
    {
      // cases here
    }
    return 1;
  }

That is how the compiler reads it, which puts OnPlayerCommandText into previous callback...
