The value of NetHrs is not passing into Model variable from the javascript function. My model class  has  the following variable.  The net Hrs is showing there on the html, but the value is not available in the controller model variable

public class BreakDownLogEntryModel
    {
         public decimal NetHrs;
}

Controller

public IActionResult BreakDownLogEntry(BreakDownLogEntryModel BreakDownLog)
        {
            if (HttpContext.Session.GetInt32("UserID") != null)
            {
                 
                if (BreakDownLog.NetHrs == 0) // Here the value is not coming .  BreakDownLog.NetHrs is always zero. Please can you help
                {
                    ViewBag.Error = "Hrs  must be given";
                }
}
}
