Use parameter in AddDays Heater

I'm using this .NET Script heater (Execute Per Row) and it seems to be working fine:

---

public object DoWork()
{
    if (InValues.Length == 0)
    throw new ArgumentException("min. 1 input parameters expected!");
    
    DateTime mydate = (DateTime)InValues[0].GetDateTime();    //order date
    bool prior2 = (bool)InValues[1].GetBool();                             //prior to 2pm
    int myday = (int)mydate.DayOfWeek;
    int ret = 1;
    int days = 1;

    switch (myday)
    {
        case 5: //friday add 3 days if after 2pm
            if (prior2 == false)
                ret = 3;
                break;
        case 6: //saturday add 2 days
            ret = 2;
            break;
    }
    //set flowheater parameter days to advance export date
      Parameter["days"].Value = ret;
    return null;
}

---

The problem is with the parameter $days$ in the number value field in the AddDays heater.
I get this error on the first row:

H: AddDays    The value [$days$] could not be converted into a number.

If I'm unable to use the parameter in the AddDays heater would I be able to calculate the date add in the .NET heater and return that value?
 

Usually “Each row Heaters” should be executed before common heaters are processed. But in case you using conditions ( IF-THEN-ELSE Heater ) or for example Set Parameter Heater and this chain triggers the AddDays Heater the FlowHeater Parameter DAYS isn´t right initialized. In this case you´re always using the calculated DAYS from the previous record!

If modified your script, see below. Now the .NET Script Heater returns the calculated date. Please have a look to the attached example.

Thanks Robert,

The .NET Script got me where I needed to be.
