Let me know if this works for you. Your goal wasn't entirely clear to me, so if it doesn't address your specific goal then let me know.
I left comments in the code to explain what I'm doing.
I tested out this code, and I think it's doing what you want. I used constants instead of reading from textboxes because it's easier for me to test, so don't just copy/paste everything verbatim and expect it to work exactly as you're intending it to. You'll need to modify some parts to suit your needs.
Option Explicit
Public Sub test()
'i prefer to keep all my variable declarations at the top
'unless i have a specific reason for not doing so
Dim emptyRow As Long
Dim ws As Worksheet
Dim y As Long
Dim wsHeight As Long
Dim found As Boolean
'just some constants i made to make testing easier for me
Const wsName As String = "Micrux"
Const combo1Val As String = "some text"
Const textbox1Val As String = "textbox1 text"
Const textbox2Val As String = "textbox2 text"
Const textbox3Val As String = "textbox3 text"
Const combo2Val As String = "combo2 text"
'dont set references to sheets like this
' Set ws = ActiveSheet
' ActiveSheet.Name = "Micrux"
'this is better method
Set ws = ThisWorkbook.Worksheets(wsName)
'or alternatively this works too
' Set ws = ThisWorkbook.Worksheets(someWorksheetNumber)
With ws
'descriptive variables are easier to read than non-descriptive
'variables
wsHeight = .Range("A" & .Rows.Count).End(xlUp).Row
'you'll need to keep changing wsHeight, so a for loop
'won't suffice
y = 1
While y <= wsHeight
If .Cells(y, 1).Value = combo1Val Then
'dont assign values like this
' .Cells(y, 4) = textbox1Val
' .Cells(y, 7) = textbox2Val
' .Cells(y, 6) = textbox3Val
' .Cells(y, 5) = combo2Val
'assign values like this
.Cells(y, 4).Value = textbox1Val
.Cells(y, 7).Value = textbox2Val
.Cells(y, 6).Value = textbox3Val
.Cells(y, 5).Value = combo2Val
'insert a blank row
.Cells(y, 1).Offset(1, 0).EntireRow.Insert shift:=xlDown
'since you inserted a blank row, you need to also
'increase the worksheet height by 1
wsHeight = wsHeight + 1
End If
y = y + 1
Wend
End With
'idk what this does but i dont like the looks of it
' Unload Me
End Sub
Hope it helps
