Strange things in menus

[Lonsofore]

It's again me. I'm making menu of weapons and I found a problem. This code works perfect:

		#ifndef DRAW_WEAPON_ITEM
#define DRAW_WEAPON_ITEM(_key, _name) \
    itemDef \
    { \
        name            "button_" ## #_name \
        visible            1 \
        rect            ORIGIN_CHOICE ## _key 128 24 \
        forecolor        GLOBAL_UNFOCUSED_COLOR \
        dvar            "ui_weapon_" ## #_name \
        textfont        UI_FONT_NORMAL \
        textscale        .25 \
        textstyle        ITEM_TEXTSTYLE_SHADOWED \
        textalignx        10 \
        textaligny        20 \
        action \
        { \
            play "mouse_click"; \
            scriptMenuResponse "" ## #_name; \
        } \
        onFocus \
        { \
            play "mouse_over"; \
            show _name ## _info; \
            show weapon_propertiestext; \
        } \
    } 
#endif
DRAW_WEAPON_ITEM(A, m1carbine_mp) 
	

But this doesn't work:

		#ifndef DRAW_WEAPON_ITEM
#define DRAW_WEAPON_ITEM(_key, _name) \
    itemDef \
    { \
        name            "button_" ## #_name \
        visible            1 \
        rect            ORIGIN_CHOICE ## _key 128 24 \
        forecolor        GLOBAL_UNFOCUSED_COLOR \
        dvar            "ui_weapon_" ## #_name \
        textfont        UI_FONT_NORMAL \
        textscale        .25 \
        textstyle        ITEM_TEXTSTYLE_SHADOWED \
        textalignx        10 \
        textaligny        20 \
        action \
        { \
            play "mouse_click"; \
            scriptMenuResponse "" ## #_name; \
        } \
        onFocus \
        { \
            play "mouse_over"; \
            show _name ## _info; \
            show weapon_propertiestext; \
        } \
    } 
#endif

#ifndef DRAW_WEAPON
#define DRAW_WEAPON(_key, _name) \
    DRAW_WEAPON_ITEM(_key, _name) \
#endif

DRAW_WEAPON(A, m1carbine_mp) 
	

Any ideas, why?
