Please help to fix code to loop through an array instead of a range

EDIT - I removed my original post content as I found I screwed up on an important issue - thanks to @rorya and for helping me notice my error and to @maniacb for suggesting a solution, which I am not fully sure how too implement.
I am a copy, paste and edit coder. I cannot write code from a blank page.
I have managed to get chat.openai to build the following macro for me.
NO matter what instructions I give chat.openai, it comes back with a range of errors

The bit I am interested in here is - it correctly looks for a value kw in range results. If <> it copies it to range activeResults
I want to sped it up by searching an array named resultsAarray instead of results range

This is the relevant code
Dim resultsArray As Variant
' Define range results, copy to resultsArray
' Confirm that resultsArray = results range with 2 x msgBox
Set results = ws2.Range("F2").Resize(maxRows - 1, resultsCols)
MsgBox "The size of the results range is: " & results.Rows.count & " rows and " & results.Columns.count & " columns."
ReDim resultsArray(1 To results.Rows.count, 1 To results.Columns.count)
' Copy the values from the results range to the resultsArray
resultsArray = results.Value
MsgBox "The size of resultsArray is: " & UBound(resultsArray, 1) & " rows and " & UBound(resultsArray, 2) & " columns."

....
'this is the bit I want to change, so macro searches for kw in resultsArray VS results range
' Check if the kw already exists in the "results" range
For Each cell In results
If cell.Value = kw Then
resultExists = True
Exit For
End If
Next cell

' Add the keyword and searchCol value to activeResults
If Not resultExists Then
ws2.Cells(CopyRow, activeCell.Column).Value = kw
ws2.Cells(CopyRow, activeCell.Column + 1).Value = ws1.Cells(r, searchCol).Value
CopyRow = CopyRow + 1
End If

Any help would be appreciated



Full code that works OK with results range

How/where have you sized resultsArray as an array?
