I am new to posting here. I have two sheets in one file, First sheet has column A containing numbers such as 100.10. They are sequenced but not all numbers are used this week but more could be next week. I need to extract numbers on the first sheet and list them in sheet 2. The numbers are in the middle of the first list starting at 300.51 thru 500.99. I need to use the numbers listed in sheet 2 to lookup data in sheet 1. please help. Ie.

Sheet 1 Col A Sheet 2 Col A
100.10 300.56
200.51 345.12
