I've tested and worked at me

PHP код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if(!strcmp(cmdtext, "/shop", true))
    {
        ShowPlayerDialog(playerid,99,DIALOG_STYLE_LIST,"Shop","\tVehicles\n\tWeapons","Select", "Cancel");
        SendClientMessage(playerid,red,"If the shop doesn't pop up, it is unavaible for this mission!");
        return 1;
    }
    return 0;
} 


PHP код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if(dialogid == 99) 
    { 
        if(response) 
        { 
            if(listitem == 0) 
            { 
                ShowPlayerDialog(playerid,99+1,DIALOG_STYLE_LIST,"Vehicles","\tSultan $ 20.000\n\tNew Maverick $ 25.000n\tNRG-500 $ 11.000n\tSanchez $ 10.000\r\n\tSpeeder $ 17.000\r\n\tSquallo $ 17.000","Select", "Cancel"); 
            } 
            if(listitem == 1) 
            { 
                    ShowPlayerDialog(playerid,99+2,DIALOG_STYLE_LIST,"Weapons","Knife $ 200\n\tDesert Eagle $ 12.000\n\tSawn-offs $ 25.000\n\tSMG $ 15.000\n\tM4 $ 24.000","Select", "Cancel"); 
        } 
        return 1; 
    } 
    return 1; 
}
