Helper IIIunable to reference a field from a table
Hello all,
I am pretty new to Power BI and am on a steep learning curve. I have a table that I cannot reference in a measure. I can create measures successfully referencing every other table. For example:
I have a table I have named "Current"
Trade Time Last Change % Change Open High Low Volume T1 TIme 1547758619 262.81 1.8299866 0.701198 260.01 263.915 259.96 77,245,081 17913.6646050926 01/17/2019 03:57:01 PM
I am attempting to create a new measure in another table that references the "Last" field in table "Current" but when I look for the available field [Last] I cannot find it.
Is there some naming reference that I need to add to show this table and field in creating a new measure?
Thanks to all for your help.

You cannot reference a "naked" column within a measure. In a measure there is no row context so the engine does not know what row you are referring to. Have a look at this and or this
I would also stick to always using fully qualified names for columns, i.e. TableName[ColumName] instead of just [ColumnName]. The latter is best reserved for referring to measures: [Measure]

JimB-GAHi, and thanks for reply. I cannot reference a field from one table to another in calculation.
My objective is to create a measure Total_Cost =[Last] (from Current table)-[New Price] (from Transactions
When I attempt to insert Measure =[Last] in the 'Transactions' table, the error reads
"The value for 'last' cannot be determined. Either 'last' doesn't exist or there is no current row for a column named 'last'.
I have inserted link to file Test.PBIX in dropbox to illustrate.
