Alternatively you could use a loop, keep the row number (counter should be the row number) and stop the loop when you find the first "ProjTemp".
Then it should look something like this:
Sub find()
Dim i As Integer
Dim firstTime As Integer
Dim bNotFound As Boolean
i = 1
bNotFound = True
Do While bNotFound
If Cells(i, 2).Value = "ProjTemp" Then
firstTime = i
bNotFound = false
End If
i = i + 1
Loop
End Sub
