Invalid Qualifer Error -setting Variable Using Getpivotdata

We have a very long macro that at the end sends an email to each training coordinator. Within the body of the email, we want to autopopulate the completion status from a pivot table using getpivotdata.

We first try to set the variable but get an error: [compile error:invalid qualifier].

Sheets(Summary).Select
Dim BDCompletion As String
BDCompletion = Application.PivotTableSelection.GetPivotData(A3, "Business Dev Plan Found")

And this is how we plan to incorporate the variable into the body of the email:

With OutMail
.To = "name@company.com"
.CC = ""
.BCC = ""
.Subject = CurrentSheet.Name & " Training Plan Status as of " & Format(Now, "dd-mmm-yy")
.Body = "BD is " & BDCompletion & " complete for 2007 Training Plans as of the date of this email."
.Attachments.Add Destwb.FullName
'You can add other files also like this
'.Attachments.Add ("C: est.txt")
.Send 'or use .Display
End With
