Why can't I add fields to New Measure?

[Anonymous]

Please see screenshots below. I am trying to add the field [NUM BUS DAYS] from an existing source but it won't let me. When I type '[' in the Create New Measure text box, the only field that pops is another measure previously created.

Thanks in advance

@Anonymous Can you directly select column name from the dataset after = and check

Thank you for your feedback!

Much to my frustration, it will not let me drag and drop the field in the Create New Measure textbox

When I tried to add formula   IF(('Scheduled and Arrived Appts'[NUM BUS DAYS]) <=14, 1, 0) to a New Measure

   , I get this error:

A single value for column 'NUM BUS DAYS' in table 'Scheduled and Arrived Appts' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

I was able to add this formula to a New Column instead and then use it in a New Measure

New Column : NPLESSTHAN14BUSDAYS = if([NUM BUS DAYS] <= 14,1,0)

New Measure : NP14BUSDAYS% = sum([NPLESSTHAN14BUSDAYS]) / count('Scheduled and Arrived Appts'[Appt Scheduled])

You can't have naked column names in measures. They have to be aggregated in some way.
