    float fVal = 0.0;
    uint8 bySel = 0;

    FORM_INIT(ID, EventIDShow, NULL, NULL, NULL, nFormFlgShowHelp);
    FORM_ADD_INPUT(ID, ID, 0, 50, "ID: ", 10, 0, 0, NULL, strID, 0, NULL, "Enter the ID");
    FORM_ADD_INPUT(ID, Val, 0, 80, "Value: ", 10, 0, 9999, NULL, fVal, 0, NULL, "Enter the value");
    FORM_ADD_INPUT(ID, Sel, 0, 80, "Select: ", 10, 0, 2, NULL, bySel, FORM_UINT8_SEL, "Truck|Pickup|Car", "Press SPACE to select type");

    FORM_SHOW(ID);
    FORM_RUN(ID);
    FORM_HIDE(ID);

    // strID, fVal, and bySel now contain the entered data
}

EVENT(IDShow)
{
    ClearLCD();
    DisplayText(0, 0, "ID/Value Screen");
