Manipulating Data Within A Loop

I am working on a macro that opens up a workbook, formats the data by moving columns etc and then spits out the data to different workbooks according to a string in col R (M,C,S etc). I am able to split the file into the workbooks, but it copies the whole sheet and not just the visible cells (its working via a filter). I have tried adding code into the loop to basically copy the visible cells to Sheet2 and then delete (or clear) sheet1 so that I only have the relevant data but have very interesting. This is only the first of a few procedures I would like to add within the loop. Ideally I want to have a prompt for the filename and path for each file, and also another procedure to add a number into each seperate file. If I know why I cant get this simple function to run I will, hopefully, be able to add in the other bits!

Function SplitSheets()
On Error Resume Next
Dim ws As Worksheet, source As Range, dest As Range
Dim daily As Worksheet
Dim sType(4) As String
Dim i As Integer
Dim strSaveFileas As String
sType(1) = "M"
sType(2) = "S"
sType(3) = "C"
sType(4) = "N"
Set daily = Worksheets(1)
For i = 1 To 4...................
