Need Help Pronto! Linking to worksheets conditionally!

Hey guys, so I am trying to create a workbook that links a certain row from a worksheet to a certain row on another worksheet. However, the kicker is that I need it to be able to link to worksheets that have not been created yet. For example, I need the code to logically read like "If A3 (A job identification number) is equal to a worksheets name (the same job identification number) then link cells from that worksheet to this one." Also, if this helps, the new worksheets that will be created are created using a template. Thanks so much for your help in advance! And if I need to clarify anything please let me know!
