    Thanks everyone for trying to help. I have just got it to work using the following:

    Expiry Status =
    SWITCH (TRUE(),
    'MyTable'[DaystoExpiry] =BLANK(), "No Exp. date",
    'MyTable'[DaystoExpiry] < 0, "Expired",
    'MyTable'[DaystoExpiry] < 366, "Less than 1yr",
    'MyTable'[DaystoExpiry] > 365, "More than 1yr"
    )
     
    I think the issue was the order of my logic, together with using "" when I should have been using BLANK().
     
    Got there in the end with your combined help 🙂

Kindly check the datatype of "'MyTable'[DaystoExpiry]"

 

When you are calculating null/blank values for MyTable'[DaystoExpiry] it is better to return BLANK not "" which causes to enforce column to Text datatype.

Hi FarhanAhmed

Thanks so much for getting back to me. I did substitute BLANK in the code above instead of "" - was this what you meant?

Like this: 

 

Expiry Status = SWITCH(
TRUE (),
'MyTable'[DaystoExpiry] = BLANK, "No Exp. date",
'MyTable'[DaystoExpiry] < 0, "Expired",
'MyTable'[DaystoExpiry] > 366, "Exp. date > 1 yr",
"Exp. date <= 1 yr"

 

But it is still not working, giving me an incorrect syntax error.  Can you spot what I have done wrong? Many thanks in advance!
