Dual Replace Class Labels

[cbaqir]

My current dimension is:

=Dual(If(Aggr(Sum({<Flag_CurrentStep={1}>}WORKFLOW_DURATION), REQUEST_ID) <= 120, Class(Aggr(Sum({<Flag_CurrentStep={1}>}WORKFLOW_DURATION), REQUEST_ID), 60), '>120'),
If(Aggr(Sum({<Flag_CurrentStep={1}>}WORKFLOW_DURATION), REQUEST_ID) <= 120, Class(Aggr(Sum({<Flag_CurrentStep={1}>}WORKFLOW_DURATION), REQUEST_ID), 60), 120))

and it gives me these labels:

My customer wants the labels to display (and then sort the same way) more simply:

<60

60-120

>120

I've been playing with the Dual Replace function in the dimension but can't get it to work correctly.

Thanks.

I was so close yet so far.
