Macro help please!

I have one workbook ("WB1") with two worksheets (Sheet1 & Sheet2). Each worksheet has most of the same information, and I want to create a macro that will cobine each worksheet. Also some information is different on both sheets. Here is what I want to do....I just don't know how to write the macro code.
**************
Start on "Sheet1"
Look at cell B1 (phone number) if B1 matches a phone number in "Sheet2" column A, cut the whole line from "Sheet2" and paste the line in "Sheet1" starting in F1.

Then move to line2 and go all the way through to end of file.

Does that make sense? ThankS

Please help me out. Thank you!
