Problem With My Loop(s) Being Able To Match Data?

[Ark68]

I have yet found another problem with my code as I've advanced past by last problem. Consider the code below, specifically the code highlighted in blue. I'm not receiving an error, but I feel it's putting itself into an infinate loop, and in the process, failing to provide the results I'm trying to achieve.
This is what I am aiming to do:

• Loop through each visible row of a filtered worksheet (For Each rw In filter_rng.SpecialCells(xlCellTypeVisible)) and obtain a value for the row (t=rw.row)
• Assign string variable inqseg to the value in cell "t"5 of the filtered database. In testing, assume inqseg = "[02]"
• Referring to a second worksheet (ws_form), obtain the value of flrow (flrow=Application.WorksheetFunction.Match("end", ws_form.Columns(8), 0) - 1) which is an integer representing the last row of a dataset that will be searched by this problematic code
• A second nested loop starts searching the range in ws_form between rows 9 and the last row of the search range defined by flrow (For fdest = 9 To flrow). 'fdest' represents th value of the row targeted to check
• 'fdest8' is a string variable which holds the value in cell "fdest",8 of worksheet ws_form. In testing, assume fdest8 = "[02]" and found in row 9 (fdest=9)
• This should match, resulting then in cell "fdest",8 taking on a interior color format, and it's adjacent cell being applied a font format and being unlocked.

This is the issue. It is not finding a match in the search range despite one existing. The second loop searches the search range and fails, and then the first loop kicks in to find a macth for the next visible row's data, and it fails as well. This happens for all rows of visible data despite values existing in the search range of ws_form. Then, when all the rows from loop 1 have been evaluated, it seems to repeat itself. (I haven't really tested this runtime, just in testing by stepping through the code. I've observed that after the first round it appeared to start over.

Thoughts?

Disregard all. And thank you for everyone that may have wasted their time with this.
1st thing, subtle spelling mistake in one on the variables being compared.
Also added "Exit For" to the second look to exit that second loop once a value was found. No sense looking beyond the match.

Hello Mr Excel & friends,
I continue to have an issue with the code in my OP, specifically the code highlighted in blue. There is (appears to be) something wrong with how the

For Each rw In filter_rng.SpecialCells(xlCellTypeVisible)

loop if functioning.

Replace the code highlighted in blue in my original post with this:

           With ws_data
                'Set filter_rng = .Range("A3:B" & lrow)
                Set filter_rng = ws_sdata.Range("A3:B" & lrow)
                cntsel = 0
                For Each rw In filter_rng.SpecialCells(xlCellTypeVisible)
                    t = rw.Row
                    inqseg = "[" & Format(ws_sdata.Cells(t, 5), "00") & "]"
                    flrow = Application.WorksheetFunction.Match("end", ws_form.Columns(8), 0) - 1
                    For fdest = 9 To flrow
                        fdest8 = ws_form.Cells(fdest, 8)
                        If fdest8 = inqseg Then
                            segdist = ws_sdata.Cells(t, 8)
                            tsegdist = ws_form.Cells(8, 25).Value
                            ws_form.Cells(fdest, 8).Interior.Color = ccgreen
                            ws_form.Cells(fdest, 8).Font.Color = RGB(216, 216, 216)
                            ws_form.Cells(8, 25) = tsegdist + segdist
                            ws_form.Cells(fdest, 6).Font.Color = ccgreen
                            ws_form.Cells(fdest, 6).Locked = False
                            cntsel = cntsel + 1
                            Exit For
                        End If
                    Next fdest
                Next rw
            End With

When I step through this code with 3 rows of visible data, this loop duplicates for each row. For example, visible row, row 12 (t=12), is cycled through twice. Since really only the cells are formatted, there is no really consequence, other than the incremental counter cntsel gets one additional value added to it. So, when all three visible rows are looped through (each one twice), cntsel = 6 when it should equal 3.

Is anyone able to determine why each visible line is being processed twice?
