I am trying to put into a tabular array how many minutes each category was logged for each half hour in the date range starting from 1st April for a user selected date. I want my output to look something like the following:

In the vba i am first importing the data then trying to create the output sheet in memory for calculation:

Sub ImporttoArray()
Dim FindName(3) As String

Set shtTrg = Sheets("Import Data")
shtTrg.Select

FindName(1) = "Location"
FindName(2) = "Effective DateTime"
FindName(3) = "Status"


With shtTrg
Range("A2").Select

Do Until ActiveCell = 0
ActiveCell.Offset(1, 0).Select
Loop

ActiveCell.Offset(-1, 0).Select

Edadre = ActiveCell.Address

End With


'find the column on the sheet

For i = 1 To 3
FindW = FindName(i)
Set Rng = Cells.Find(What:=FindW, After:=ActiveCell, LookIn:=xlFormulas, _
Lookat:=xlPart, SEarchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False, _
SearchFormat:=False)

If Rng Is Nothing Then
MsgBox "Check Data"
Exit Sub
End If


Rng.Select
staddress = ActiveCell.Address
Selection.End(xlDown).Select
endaddress = ActiveCell.Address

If i = 1 Then rw = ActiveCell.Row
If i <> 1 Then cw = ActiveCell.Column
If i <> 1 Then cw = endaddress = Cells(rw, cw).Address


Select Case i

Case 1
Location_A = Range(staddress, Edadre)
Case 2
DateTime_B = Range(staddress, endaddress)
Case 3
Status_C = Range(staddress, endaddress)
End Select




Next i
'Stop
End Sub

Sub Output()



Set shtTrg = Sheets("Output Expected")
shtTrg.Select

StartDate = DateValue(Sheets("Parameters").Range("B1").Value)
EndDate = DateValue(Sheets("Parameters").Range("B2").Value)

'30 min periods between dates

Duration = ((EndDate - StartDate + (1)) * 24 * 2) - 1

ReDim MyArraydatestart(Duration) As Variant
ReDim MyArraydateend(Duration) As Variant


MyArraydatestart(0) = StartDate
MyArraydateend(0) = DateAdd("n", 30, MyArraydatestart(0))

For k = 1 To Duration
MyArraydatestart(k) = DateAdd("n", 30, MyArraydatestart(k - 1))
MyArraydateend(k) = DateAdd("n", 30, MyArraydatestart(k))
Next k

For i = 0 To Duration

Cells(i + 2, 1).Value = MyArraydatestart(i)
Cells(i + 2, 2).Value = MyArraydateend(i)

Next i

End Sub

Can anyone provide some help please. the other sheet i use is the one the user will enter the start date

Sample.xlsm
