How to Conditionally Copy of Column from Another Workbook

Hi,

(1) I have sample workbook named "Database" as master database, in which I have 20 columns of data for 10 items (named A to J) with each item is having data in 2 adjacent columns
(2) I have another sample workbook named my "MyWorkbook", in which I am randomly selecting some of the 10 items e.g. 5 items in Sheet1
(3) I want to copy data of both columns pertaining to this randomly selected items from my source file (i.e. Database) and paste it to respective destination cell reference mentioned in "Column C" of my target file (i.e. MyWorkbook)

For better understanding I am attaching both sample workbooks.. Can anyone help me with VBA code for this please....
