Validate voids in columns with dates

[Syndicate_Admin]

Hello, I appreciate your great help to the following query:

I am making a formula to compare the gaps of three columns and that the result returns the value of any of the columns, but I am getting erroneous results.

Attached formula and image with formula.

UNION_FECHAS = SWITCH(TRUE(),

ISBLANK('SQVI@TD1'[SE16N])=TRUE(),

'SQVI@TD1'[MB25],

ISBLANK('SQVI@TD1'[MB25])=TRUE(),

'SQVI@TD1'[SQVI],

ISBLANK('SQVI@TD1'[SQVI])=TRUE(),

'SQVI@TD1'[SE16N])

I think the logic here is wrong. I think you wanted to take that value if not blank.

UNION_FECHAS = 
SWITCH(TRUE(),
NOT(ISBLANK('SQVI@TD1'[SE16N])),'SQVI@TD1'[SE16N],
NOT(ISBLANK('SQVI@TD1'[MB25])),'SQVI@TD1'[MB25],
NOT(ISBLANK('SQVI@TD1'[SQVI])),'SQVI@TD1'[SQVI]
)

Note that you need to change the order by yourself.

Your formula was: if the column is blank, give me that.

My formula is: if the columns is not blank, give me that.
