How to adjust a formula to incorporate within 1 day

[lennox25]

Please help - How can the below formula be adjusted to show within 1 working day of incident. Currently it just shows the total days between. I dont want to use filters. Thank you.

Within 1 Working Days of Incident (exc. Weekends/Holidays) = if(ISBLANK('Table'[Date of Incident]),BLANK()

, if(ISBLANK('Table'[Date Informed of Incident]), BLANK()

, CALCULATE(SUM('Date_Table'[IsWorkDay]),

DATESBETWEEN('Date_Table'[Date],

'Enf Delivery Tracker'[Date of Incident],

'Enf Delivery Tracker'[Date Informed of Incident])

)))-1
