I'm trying to use SUMIF formula in VBA, based on a sheet that can have diferent names. 
When I'm on this ActiveSheet (can vary), I want to add another sheet template from another workbook Template_test and put a SUMIF formula referenced to the activesheet.
When I run the macro, error occurs (1004) and stops at the formula.
This is what I have:
Sub test()
    Set CurBook = ThisWorkbook
    Dim wksheet As Worksheet
    Set wksheet = ActiveSheet
    MsgBox CurBook.Name & "_" & wksheet.Name
'Open template
    Workbooks.Open filename:= _
        "D:\Template_test.xlsm"
'Copy new sheet
    Sheets("template").Select
    Sheets("template").Copy After:=CurBook.ActiveSheet
'Close Template file
    Windows("Template_test.xlsm").Activate
    ActiveWindow.Close
 'SUMIF Formula in Template regarding wksheet in CurBook
    Range("E11").Select
    ActiveCell.FormulaR1C1 = _
        "=SUMIF('& wksheet &!C2,""=P-SEC"",'& wksheet &!C16)" End Sub
Is there a way to solve this and make it work?
