Summary Tab VBA - Using Formulas Taken From New Tabs

I am currently working through a macro and got stuck about halfway. I have a number of files in a folder on my drive that I am pulling the first tab from into a Master workbook, and then I want to have a summary tab for all of those tabs(they are all identical). Some of the cells will be text(say range A5:C105), some will be SUM(E6:G105) and some will be AVERAGE(D6:D104) formulas needed. These formulas will not change, but will need to pull the data from all tabs that are pulled into the file.

So far I have this code that pulls all of the first tabs together:

Code:

Sub Staff_Plan_Update()
Dim wbDst As Workbook
Dim wbSrc As Workbook
Dim wsSrc As Worksheet
Dim MyPath As String
Dim strFilename As String

Call TimeStamp

[Code] ......

I was going to record a macro that creates a summary table every time, but not sure if it is easier to create a blank template for the summary tab that will update every time all of the tabs are pulled into this file. The problem I ran across with that is that I will be taking the SUM of all tabs, but the number of tabs/name of tabs will be different.
