Compare 1st 8 digits of rows in three worksheets

[NeedExcelHelp07]

I have 3 worksheets of data. The master worksheets is called ipc. The other
two worksheets are called, vb and pb.
Each row cell is 14 characters long.
IPC is the master worksheet and I want to match the data in row D up to the
first 8 chracters in worksheets vb and/or pb. In column f in worksheet ipc,
if there is a match between the first 8 characters in row d in vb or pb, I
want row d from the match row to be displayed on row f. If there's no match,
it can say FALSE.

I'm looking for any formula or function to make this work.

Thanks!
