Copying And Pasting Multiple Worksheets Into One Sheet

I'm writing code which will copy multiple sheets of information in a workbook (from a report) and trying to paste it onto one sheet in another document where I can further manipulate the data. Here's my code, I've made some mistakes, and I've just been banging my head against the screen try to fix it. I'm erroring at ActiveCell. Offset(1, 0).Range("A1").Select. I'm trying to paste it all in one sheet at the next blank cell in the sheet and then close the document after it's all been pasted.

Sub OpenDataSheet()
'Opens CSS Report
Workbooks.Open Filename:="C:Documents and SettingseichornjDesktopTest and Destroy est and destroy CSS.xls"
'Delete first two sheets of CSS report
Application.DisplayAlerts = False
Worksheets( Array(1, 2)).Delete
Dim mySheet As Worksheet
For Each mySheet In Worksheets
mySheet.Select
'Delete unneeded rows of CSS report
