Frequently Used code

Hey Everyone,

I'm using a workbook with lots of macros doing all sorts of magic for me. Aside from "update this" and "look up that" here and there, by far the most frequent type of macro is one that moves information from the active sheet to a "transactions" sheet - this is to consolidate the data from many different sources and helps create inventory and analysis. I'm quite proud of what i've done, really (and acknowledge that you guys on here helped me learn the new stuff i needed).

Here's the question,

There are 4 worksheets for data entry and each one currently has it's own sub, assigned to a button that processes the entries into the transactions. The code does this:

    Application.ScreenUpdating = False
        
        
    
    'add transaction info for date/time etc.
    
    
    Sheets("entry").Range("AB28:ae77").Value = Sheets("Admin").Range("J8:m8").Value
    
    Sheets("admin").Range("j6").Value = Sheets("admin").Range("j6").Value + 1
    
    Sheets("entry").Activate
    
    Range("B28:Ai77").Copy
    
    Sheets("Transactions").Select
    
        If ActiveSheet.FilterMode Then
            ActiveSheet.ShowAllData
        End If
        
        
    Range("A1").Select
    Selection.End(xlDown).Select
    Selection.Offset(1, 0).Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Sheets("Admin").Select
    Range("L6").Copy
    Range("J6").PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Sheets("Entry").Select
    Call EntryCancel
        Application.ScreenUpdating = True


End Sub

This is an example of the code but there are at least 3 other sheets that feature very similar subs. I've been reading about good practice in programming and it says that repeatedly used code should be put into it's own private sub and called by the other subs that use it. The problem is that there are things in this code that are variable, such as the row number where the data starts (in "entry" it is row 28:77, but "online" is range 9:86). I understand that the sub NAME () brackets can be used to "pass" the sub some variables, but haven't been able to properly consolidate this code into it's own private sub.

Where, or how, do i define a variable to identify the first row that the macro looks at in each sheet? I've tried this sub as the one that activates when the confirm button is clicked:

sub Entry_Confirm()

set EntryFirstRow = 28

call Transaction_Process(entryfirstrow)

end sub

but that doesn't work for anything!

Help is appreciated.

Edited to add: p.s I know that the consolidated code will also need to have a defined variable to know which sheet to switch back to - as the code above keeps switching to the "entry" sheet, i'm assuming that passing the variable for the first row, and the sheet of origin will be the same.
