VBa vlookup , replace range as variable - excel

Question

OK I will reformulate the question.
I have a worksheet with a tab named"My INT".
This tab contains a data table and a button with an assigned macro called "importRMR". code below:
Sub importRMR()
Dim rng As Range
Set rng = ActiveSheet.Range("G3")
Sheets.Add(After:=ActiveSheet).Name = "RMR " & Format(Date, "DD-MM-YY")
ActiveSheet.Buttons.Add(966.75, 27.75, 153.75, 125.25).Select
Selection.OnAction = "Cimp"
Selection.Characters.Text = "Importuj"
With Selection.Characters(Start:=1, Length:=13).Font
.Name = "Tahoma"
.FontStyle = "Standaard"
.Size = 16
.Strikethrough = False
.Superscript = False
.Subscript = False
.OutlineFont = False
.Shadow = False
.Underline = xlUnderlineStyleNone
End With
End Sub
This creates a tab with a specific name :RMR " & Format(Date, "DD-MM-YY")
NOw I manually paste the table( always identical ) to the newly created tab "RMR 03/08/2018". the next step is to click the button in this tab ( Importuj) and the result I am aiming for is to :
1. Vlookup data in tab "my INT" where the range( lookup array) is tab "RMR" and then delete the rmr tab.
such procedures like triming the data pasting values and so on I am able to do, just the vlookup but is a problem.
my current code for "importuj " button is:
ub TEST()
Dim DOTR As String
Dim shT As String
Set shT = Sheets(DOTR).Range("E2:H584")
'shT = Sheets(DOTR).Range("c1:e2").Select
DOTR = "RMR " & Format(Date, "DD-MM-YY")
'Sheets(DOTR).Range ("E2:H584").selc
Worksheets("My INT").Range("N3").Formula = "=vlookup(c3,sht,3,0)"
End Sub
Unfortunately, I get an error - "Compile Error" - Object required.

The goal is to combine several different strings into a one cohesive string:
=VLOOKUP(C3,'ABCDEF 03-08-18'!$B$4:$D$10,3,0)
That will be placed inside a cell using:
Worksheet.Range.Formula
The worksheet name "ABCDEF" is arbitrary and we create the date on the fly. We use a named range in Excel "myNamedRange" and reference the address property to allow flexibility without editing code.
Dim strSheetName As String
Dim strNamedRange As String
Dim strDateSegment As String
Dim strPrefix As String
Dim shT As String
strSheetName = "My INT"
strNamedRange = "myNamedRange"
strDateSegment = Format(Day(Date), "00") & "-" & Format(Month(Date), "00") & "-" & Right(Year(Date), 2) & "'!"
strPrefix = "'" & "ABCDEF"
shT = "=VLOOKUP(C3," & strPrefix & strDateSegment & Worksheets(strSheetName).Range(strNamedRange).Address & ",3,0)"
Worksheets("My INT").Range("N3").Formula = shT
