Calculated Column with multiple conditions

[Anonymous]

i have a table with following columns.

                                                                                             Leave Details

EmployeeName      Leave taken days     Leave Type           Start Date         End Date      Month diff      Created colum

   A                               5                        Work from home      24/12/2018        29/12/2018          1                 0

   B                              120                     Vacation Leave          01/06/2018        31/122018           6                 0

   C                              10                       Marraige leave          01/06/2018       10/06/2018          1                 5

work from home should not consider as a leave, return created column as 0

marraige leave should not consider as a leave if leave taken days <5, want remaining days if leave taken days >5 in a created column.

vacation leave should not consider as a leave if month diffe <=6, return created column as 0.

i tried the following dax  query:

Created Column =
SWITCH(TRUE(),
'Leave Details'[Request type] = "Work From Home" && 'Leave Details'[Leave taken days] >0,0,
'Leave Details'[Request type] = "Vacation Leave" && 'Leave Details'[Month diff]=6,'Leave Details'[Month diff]= -6,
'Leave Details'[Request type] = "Marriage" && 'Leave Details'[Leave taken days]>=5,'Leave Details'[Leave taken days] - 5,
'Leave Details'[Request type] = "Vacation Leave" && 'Leave Details'[Month diff]<6,0,
'Leave Details'[Request type] = "Marriage" && 'Leave Details'[Leave taken days]<5,0,
'Leave Details'[Leave taken days]
)

error Occurs :  Expressions that yield variant data-type cannot be used to define calculated columns.

@Anonymous,

You may remove the equal sign (=) in expression below.

'Leave Details'[Month diff]= -6,

@Anonymous

please try if formula instead of switch. It should fit your requirement. Thanks

Column = 
    if(Sheet2[leavetype]="a"&&Sheet2[leave taken days]>0,0,
        if(Sheet2[leavetype]="b"&&'Sheet2'[month diff]=6,Sheet2[month diff]-6
            ,if(Sheet2[leavetype]="c"&&Sheet2[leave taken days]>=5,Sheet2[month diff]-5,111)))
