If and Vlookup

I am new to PowerBI and DAX. I am trying to create an aging report for open IT tickets. 

My table contains the number of days that the ticket has been open, but I need to return a value (see status message below) based on the number of days that the ticket has been open. 

I was able to do this in EXCEL using this formula =VLOOKUP(IF(TODAY()>'IS SR  - Dec Data List All'!$J2,TODAY()-'IS SR  - Dec Data List All'!$J2,0),Age_Range1,2,TRUE)  where J2 is the ticket entry date

Age_Range1 has the following:

How do I do this in PowerBI?

Thanks for your help :-)
