Count Duplicates Within a Range of Values

Hello,

Looking for a solution to my issue currently I am trying to have a duplicate count to display when a room is occupied within a duration of time 

Example I want rooms that are the same that have the same room on the same day within the same time range to be counted as a duplicate not just when its start and end time are the same.

Try this calculated column

 

Duplicate Test =
VAR CurrentStart = TableName[Date/Start Time Required]
VAR CurrentEnd = TableName[Date/End Time Required]
RETURN
    CALCULATE (
        COUNTROWS ( TableName ),
        FILTER (
            ALLEXCEPT ( TableName, TableName[Room (Option 1)], TableName[Date Rqeuired] ),
            OR (
                TableName[Date/Start Time Required] > CurrentStart
                    && TableName[Date/Start Time Required] < CurrentEnd,
                TableName[Date/End Time Required] > CurrentStart
                    && TableName[Date/End Time Required] < CurrentEnd
            )
        )
    )

@Zubair_Muhammad
I'm not the most familiar with DAX but that returned this warning
A single value for column 'Date/Start-Time Required' in table 'Overlapping' 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.

You tried adding it as a MEASURE....

 

The formula I wrote was for a calculated colum

There is an option to add Column as well...Please use that OPTION

Thank you for the help with this, I am very new to power BI, but seem to still have an issue with this calculable column it is complaining about a 'Token Eof Expected' on VAR CurrentStart
My code currently looks like this:

Duplicate Test 
=
VAR CurrentStart = Overlapping[#"Date/Start-Time Required"]
VAR CurrentEnd = Overlapping[#"Date/End-Time Required"]
RETURN
    CALCULATE (
        COUNTROWS ( Overlapping),
        FILTER (
            ALLEXCEPT ( Overlapping, Overlapping[#"Room (Option 1)"], Overlapping[Date Required] ),
            OR (
                Overlapping[#"Date/Start-Time Required"] > CurrentStart
                    && Overlapping[#"Date/Start-Time Required"] < CurrentEnd,
                Overlapping[#"Date/End-Time Required"] > CurrentStart
                    && Overlapping[#"Date/End-Time Required"] < CurrentEnd
            )
        )
    )
