Vba comparing then copying two different Sheets - excel

Question

I realize there are a few different similar ideas on here. But I need help with this simple compare function.
My goal is to compare two different cells and if they are the same, replace it with its full non-abbreviated name.
Thank you for your time!!!
I.E
Sheet1 Sheet2
Column H Column A Column B
Dept Dept Department
This is what I have (Yes simple), but the cell H is not updating to the non-abbreviation:
Sub updateDeptNames()
'Format user ID from the email column
Dim ws As Worksheet, ws2 As Worksheet
Dim LastRow As Long, i As Long
Dim tmpArray() As String, tempDept As String
Set ws = ActiveWorkbook.Sheets("Student_Travel_DB") '--> This is the relevant sheet
Set ws2 = ActiveWorkbook.Sheets("gokoutd") '--> This is the relevant sheet
LastRow = 1000 ''Bug finding the last row, had to hard code it
For i = 2 To LastRow 'Iterate through all the rows in the sheet
For j = 2 To 112
tempDept = ws2.Range("A" & j).Value
If ws.Range("H" & i).Value = tempDept Then
ws.Range("H" & i) = ws2.Range("B" & j).Value
End If
Next j
Next i
End Sub

You can more easily use VLOOKUP either on your worksheet or with VBA:
Sub GetFullName()
Dim cl As Range, data As Range, lookUpRng As Range
Set data = Worksheets("Student_Travel_DB").Range("A1:A10")
Set lookUpRng = Worksheets("gokoutd").Range("A1:B10")
On Error Resume Next
For Each cl In data
cl = WorksheetFunction.VLookup(cl, lookUpRng, 2, False)
Next cl
End Sub
You'll need to change your range references.
