It's hard to tell why it's not working without some code to look at it.  At a minimum, what does your value_string array look like, how are you attempting to add the "cnp code" to your flags_tree, and what is the hf_register_info array entry where VALS is used?
You should have something like the following:
static int hf_yourproto_flags_code = -1;
static const value_string code_vals[] = {
    {0x00, "CNP"},
    {0x01, "CNP2"},
    {0x02, "CNP3"},
    {0, NULL}
static gboolean dissect_yourproto(...) {
    proto_tree_add_item(flags_tree, hf_yourproto_flags_code, tvb, offset, 1, FALSE);
void proto_register_yourproto(void) {
    static hf_register_info hf[] = {
            {"Code", "yourproto.flags.code", FT_UINT8, BASE_HEX,
            VALS(code_vals), 0x1F, "", HFILL}},
Hope it helps.  If not, I suggest you post your code.

Subject: [Wireshark-dev] VALS

When Bitweise decoding, I wille an issue as follows: 
The decoding is for 0x00 like: 
0 ... ....: Flag 1: Not Set 
..0 .. ....: Flag 2: Not Set 
... 0 ....: Flag 3: Not Set 
.... 0 0000: CODE: (0x00) CNP 
If CODE (lezte 5 bits) = 00000 (0x00) is CNP, 
If CODE = 00001 (0x01) CNP2 
If CODE = 00010 (0x02) CNP3 

I have tried it with VALS but it does not work. 
PLEASE help me. 
Thank you
