.FindNext failing after a .Find function (excel vb

问题:

I am trying to use .Find and .FindNext to search through a single column of data. I first need to find the first cell containing the value "Total". The cell I'm trying to get to is the third cell AFTER the "Total" cell to contain the value "Tech". It is known for certain that the Cells(1, 1) does not contain "Tech" or "Total".

Dim FirstTotal As Range
Dim SearchRng As Range
Dim ResultRng As Range
Set SearchRng = Range("A:A")

Set FirstTotal = SearchRng.Find(What:="Total", After:=Cells(1, 1), SearchDirection:=xlNext)
Set ResultRng = SearchRng.Find(What:="Tech", After:=FirstTotal, SearchDirection:=xlNext)
SearchRng.FindNext().Activate
SearchRng.FindNext().Activate

About 50% of the times I've run this code, I've been stopped by a type mismatch error on the line beginning with Set ResultRng =. The rest of the time, the code has run all the way through, but the results look as though the final two lines of code were ignored completely.

I suspect that the answer here is pretty elementary, but I'm pretty new to excel vba and no resources I've found so far have answered this. Please help!

If "Total" isn't found, then FirstTotal will be Nothing, which will result in a Type Mismatch when you try to use FirstTotal for the "After" argument in the ResultRange Find (the 2nd line). This will prevent that error:

Set FirstTotal = SearchRng.Find(What:="Total", After:=Cells(1, 1), SearchDirection:=xlNext)
If Not FirstTotal is Nothing Then
   Set ResultRng = SearchRng.Find(What:="Tech", After:=FirstTotal, SearchDirection:=xlNext)
End If

Generally speaking any dependent Finds need to be treated this way.

Clearly, some kind of Else statement is required here, but I don't know what that would be.
