php
forward CreatePlayerUcp(playerid);
public CreatePlayerUcp(playerid)
{
    new str[500];
    strcat(str, ""COL_WHITE"Sila Masukkan Nama Character "COL_RED"Roleplay "COL_WHITE"Anda.\nSila Pastikan Nama Anda Mempunyai Underscore "COL_YELLOW"'_' "COL_WHITE".\n");
    strcat(str, ""COL_WHITE"Pastikan Nama Anda Berunsur Roleplay(Nama Betul Dan Wujud) Bukan Berunsur Lucah!");
    ShowPlayerDialog(playerid, DIALOG_CREATECHARACTER, DIALOG_STYLE_INPUT, "Create UCP Account", str, "Create", "Cancel");
    return 1;
}

php
if(dialogid == DIALOG_CREATECHARACTER)
    {
        if(!response) return Kick(playerid);
        if(response)
        {
            if(!CheckRPName(inputtext))
            {
                CreatePlayerUcp(playerid);
                SendClientMessage(playerid, -1, ""COL_RED"ERROR:"COL_WHITE"Nama Anda Tidak Berdasarkan Roleplay!");
            }
            if(PlayerUcp[playerid][pUcp1] == 0)
            {
                SendClientMessage(playerid, -1, "Loaded Ucp Slot 1!");
                PlayerUcp[playerid][pUcp1] = 1;
                strmid(PlayerUcp[playerid][pUcp1Name], inputtext, false, strlen(inputtext), MAX_PLAYER_NAME);
                OnCharacterCreate(playerid, inputtext);
                return 1;
            }
        }
        return 1;
    }

So the problem is. the dialogid isnt functioning. only CheckRPName is working. it doesnt send text Loaded UCP Slot 1 at all
