Open Customer Form Customization

We upgraded from 10.2.200.27 to 10.2.400.5 this weekend. This is about our only outstanding issue.
This customization opens up a trimmed down version of customer tracker so that order entry can verify customer notes. This opens up from order entry after a customer is selected.

We now receive an error message when the form opens. The form still opens and the record is retrieved but . . ?
Any ideas?

I appreciate the help.

Form Load of the customer tracker form:

private void CustomerTrackerForm_Load(object sender, EventArgs args)
	{
		CustomerAdapter adCustomer = new CustomerAdapter(this.oTrans);
		//also need to add a reference for this
		//Erp.Adapters.Customer
		string inCustNum;	

			adCustomer.BOConnect();
				if (CustomerTrackerForm.LaunchFormOptions != null)
				{	
				    if (CustomerTrackerForm.LaunchFormOptions.ValueIn != null)			
				    {	
						inCustNum = Convert.ToString(CustomerTrackerForm.LaunchFormOptions.ValueIn);        
						if (oTrans.CustomerAdapter.GetByCustID(inCustNum,true) == true)
						{		           			
							SearchOptions searchOpts = new SearchOptions(SearchMode.AutoSearch);
				            bool blnMorePages = true;
							searchOpts.DataSetMode = DataSetMode.RowsDataSet;
				            searchOpts.PreLoadSearchFilter = "CustID = '" + inCustNum + "'";
				            oTrans.InvokeSearch(searchOpts);
				            oTrans.CustomerAdapter.GetRows(searchOpts, out blnMorePages);
				            searchOpts = null;										
				        }	
				    }
				} 
			adCustomer.Dispose();
	}


Order Entry Form:
	private void epiTextBoxC2_ValueChanged(object sender, System.EventArgs args)
	{
		/**/
			string cust = epiTextBoxC2.Text;
			EpiTextBox soTextBox =(EpiTextBox)csm.GetNativeControlReference("4fceeeec-518c-4256-932e-34a4c1a584ee");

			if (cust.Length != 0 & soTextBox.Text == "0" & cust!="1005596")
			{
				LaunchFormOptions lfo = new LaunchFormOptions();
				lfo.ValueIn=cust;
				lfo.IsModal = true;
				ProcessCaller.LaunchForm(oTrans, "UDCustTr",lfo);		
			}	
		
	}
