v7.5.3 Web --

Have a custom tab with a date field on it that needs to be 5 days greater than the EstimatedClose date if the opportunity is still open, or 5 days greater than the ActualClose date if opportunity is closed.  When I add the code below to the load action for the form, it errors out and won't load, but I can't get any sort of error message to show me what isn't working correctly.

<p>Sage.Entity.Interfaces.IOpportunity objOpp1 = Bindingsource.Current as Sage.Entity.Interfaces.IOpportunity;

DateTime EstDate = new DateTime();
DateTime ActClose = new DateTime();
EstDate = objOpp1.EstimatedClose;
ActClose = objOpp1.ActualClose;
 
if (objOpp1.Closed == "T")
{
    objOpp1.GoLiveDate = EstDate.AddDays(5);
}
Else 
{
    if (objOpp1.GoLiveDate == null || objOpp1.GoLiveDate < ActClose.AddDays(5))
    {
         objOpp1.GoLiveDate = ActClose.AddDays(5);
    }
}

Your code is assuming that the Estimated and Actual Close dates are not NULL, I would suggest you check them first.

In addition to what Raul said, if those are nullable values you can use stuff like if objOpp1.EstDate.HasValue, etc

BTW, what is the error message you are getting?

Thanks for the reply.  I checked for the nulls which is an obvious miss on my part an still having problems.

My biggest frustration is that I can't get an error message to display.  All I get is a blank page.  I see the gradient image, but no text/controls/menus, etc show up on the page and no error message.

Here's my code now: 

Sage.Entity.Interfaces.IOpportunity objOpp1 = BindingSource.Current as Sage.Entity.Interfaces.IOpportunity;

DateTime EstDate = new DateTime();

if (objOpp1.EstimatedClose.HasValue)
{
    EstDate = Convert.ToDateTime(objOpp1.EstimatedClose);
}
   else
{
    EstDate = DateTime.Now;
} 
DateTime ActClose = new DateTime();
ActClose = Convert.ToDateTime(objOpp1.ActualClose);
if (objOpp1.ActualClose.HasValue)
{
   ActClose = Convert.ToDateTime(objOpp1.ActualClose);
}
else
{
   ActClose = DateTime.Now;
}
if (objOpp1.Closed == 'T')
   {
        objOpp1.GoLiveDate = tempDate.AddDays(5);
   }
   else
   {
 if (objOpp1.GoLiveDate == null || objOpp1.GoLiveDate < ActClose.AddDays(5))
    {
         objOpp1.GoLiveDate = ActClose.AddDays(5);
    } 
}

Actually, line 21 should read "objOpp1.GoLiveDate = EstDate.AddDays(5);

Presumably you've tried forcing this into a debugging session, ie (effectively) putting a 'stop' near the beginning of your code?

So, Here's the final, working code.  Key difference was how I was addressing the "Closed" field in the Opportunity.  I was looking for the text value "T", where the AA wanted me to use the logical value of "true".  Condensed the code a bit, but now works as expected.

thanks for the help.

Sage.Entity.Interfaces.IOpportunity objOpp1=BindingSource.Current as Sage.Entity.Interfaces.IOpportunity;
DateTime tempDate=new DateTime();
tempDate = Convert.ToDateTime(objOpp1.EstimatedClose);

DateTime ActClose=new DateTime();
ActClose = Convert.ToDateTime(objOpp1.ActualClose);

if (objOpp1.Closed!=true)
{
    objOpp1.GoLiveDate=tempDate.AddDays(5);
}
else
{
     if(objOpp1.GoLiveDate==null || objOpp1.GoLiveDate<ActClose.AddDays(5))
    {
        objOpp1.GoLiveDate=ActClose.AddDays(5);
    }
}

Nice one, well done.

Another option that I always use is the GetValueOrDefault to ensure the date is not null for example:

   objOpp1.ActualClose = objOpp1.ActualClose.GetValueOrDefault(SystemDateTime.UtcNow);

   objOpp1.GoLiveDate = objOpp1.ActualClose.GetValueOrDefault(SystemDateTime.UtcNow).AddDays(5);
