Using For each loop fails to loop through worksheets - excel

Question

Hi I have been trying to join together several macros to automate a process which involves importing data files from text and copying parts of the data to a "core sheet". My problem arises when i try to use the "For Each loop" to move through the sheets check a condition and if the condition is met run the data extraction macro. Basically the macro does not loop, i researched various solutions but nothing worked. It works fine the first time it is run (usualy the sheet that is displayed meets the conditions so it moves on to the "shima" macro) however then the "core sheet" is displayed and since this does not meet the conditions i just want it to move on to the next sheet but it doesn't. Code is below let me know if any of this is unclear.
Sub FullAuto()
Call Module1.Myfolderselector 'this macro imports all the text file in a given folder
Dim Msg, Style, Title, Response, MyString
Public ws As Worksheet
Msg = "Yes for Fluorescence, No for UV"
Style = vbYesNo + vbCritical + vbDefaultButton1
Title = "Choose data"
'this parts asks the user which type of Data they want to import
Response = MsgBox(Msg, Style, Title)
If Response = vbYes Then
MyString = "Yes"
Else
MyString = "No"
End If
For Each ws In Worksheets 'this is the part with issues.
If MyString = "Yes" And Range("A1").Value <> "Core" Then
Call Module1.Detector_B_Shima_9_0
ElseIf MyString = "No" And Range("A1").Value <> "Core" Then
Call Module1.Detector_A_Shima_9_1
End If
Next ws
Worksheets.Add(After:=Worksheets(1)).Name = "Plot Sheet"
End Sub
Sub Detector_B_Shima_9_0()
Cells.Select
Selection.Find(What:="[LC Chromatogram(Detector B-Ch1)]", After:=ActiveCell _
, LookIn:=xlFormulas, LookAt:=xlPart, SearchOrder:=xlByRows, _
SearchDirection:=xlNext, MatchCase:=False).Activate
ActiveCell.Offset(9, 1).Select
ActiveCell.Value = Range("B20")
Range(ActiveCell, Cells(ActiveCell.Row + 8401, ActiveCell.Column)).Select
Selection.Copy
Sheets("Core Sheet").Select
Range("C3").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
ActiveCell.EntireColumn.Insert
End Sub

Try to change this code:
For Each ws In Worksheets 'this is the part with issues.
If MyString = "Yes" And Range("A1").Value <> "Core" Then
Call Module1.Detector_B_Shima_9_0
ElseIf MyString = "No" And Range("A1").Value <> "Core" Then
Call Module1.Detector_A_Shima_9_1
End If
Next ws
to the next one
For Each ws In Worksheets
If MyString = "Yes" And ws.Range("A1").Value <> "Core" Then
Call Module1.Detector_B_Shima_9_0
ElseIf MyString = "No" And ws.Range("A1").Value <> "Core" Then
Call Module1.Detector_A_Shima_9_1
End If
Next ws
Note, that I've added ws. before Range("A1") : ws.Range("A1").Value. This little improvment helps VBA to understand, that Range("A1") belongs to worksheet ws.
