Conditional Median Formula

I have two columns of data for 1,472 data samples: Column A has numerical identifiers for job types and those numbers are 1 through 29. Column B has elapse times to complete those ID #'s in Column A. I have a table set up with 29 rows for each of the Job ID, 1 through 29 and those ID's are in column A. In the same table in column B, I've placed a conditional median formula that SHOULD calc the median time for each Job ID found in the data table of 1,472 entries. Here's the formula I'm using which I actually found here in another thread:

=MEDIAN(IF((DATA!$A:$A=1),DATA!$B:$B))

Unfortunately, I get zero values for all the Job ID numbers. All number formats are correct.

What am I doing wrong?
