Nested IFs

I would like to have excel look at column b and return the values in column a if there is a value in column b.

Here is what started with, but I am very new at excel.

=IF(ISTEXT(Schedule!B12),Schedule!A12,(IF(ISTEXT(Schedule!B16),Schedule!A16)))

I am trying to do this for 8 rows and only want it to populate if there is a value in column B

I can get it to populate with blanks, but I would like it only to populate when there is a value.

Thanks in advance.
