Error 1004 when using =AND(ISERROR) formula in macro - vba

Question

I'm recording a macro to automate some Excel reports and have encountered the following bug whenever I try and run an iserror(search) formula:
Run-time error '1004': Application-defined or object-defined error
I have two lists. The formula iterates through the first list and compares the values with those of the second list, hiding any matching values.
The formula in Excel is like this only with a wider criteria range:
=AND(ISERROR(SEARCH($B$3212,B2)),ISERROR(SEARCH($B$3213,B2)))
It works perfectly when I insert the formula directly into the spreadsheet cell however I get an error when I record and later run the macro using the same formula.
EDIT 2
I got the formula insertion to work through the macro but now I cannot filter the data as before, even when I do it manually without the macro.
Below is a link to a picture giving an example of the type of lookup I'm trying to achieve, previously it worked perfectly and removed all the rows which contained a string from the 'to remove list' now I cannot get it to filter at all. I've tried removing the macro after saving in notepad in case the file had become corrupted but it still does not filter as before. What could be causing this?
This is how the lookup works
Cell [A13] would contain the aforementioned ISERROR formula in this example.

Answer 1

This formula doesn't translate well to VBA in its current form. You should use the VBA Instr function instead of the worksheet function Search.
Function FindSubstring() As Boolean
Dim rngFindText As Range
Dim rngWithinText As Range
Set rngFindText = Sheet1.Range("B3212")
Set rngWithinText = Sheet1.Range("B2")
FindSubstring = InStr(rngWithinText, rngFindText)
End Function
Sub foobar()
Debug.Print FindSubstring
End Sub

Answer 2

You are asking Excel a question to tell you to find the contents of $B$3212 in B2 and to find if again.
Usually the SEARCH is used to find the contents of one thing in another, by using it again the AND statement you are asking it again ... and for what?
Hence the question does not make sense.
What I think you might be asking if just once and if there is an error meaning it did not find it there in this instance for it to return 0.
=IF(ISERROR(SEARCH($B$3212,B2)),0,SEARCH($B$3212,B2))

Answer 3

I figured this one out, the original 1004 error was caused by vba only partially recording the formula, the solution involved simply going into the debugger to find which line hadn't been translated correctly and editing that line. I then had to edit the formula so as to be able to filter out values acording to my criteria and ended up with a formula closer to this:
=AND(ISERROR(SEARCH("Value1",B2)), ISERROR(SEARCH("Value2",B2)))
