Help with PowerQuery syntax using "if" and "and"

[Anonymous]

Good morning, other threads didn't help me with my syntax which is throwing an "Error".  I'm creating a custom column in PowerQuery.

=if ([Part Type]="TC" and [Part Size]<7) then 2

     else if ([Part Type]="TC" and [Part Size]>13.38) then 2

       else if ([Part Type]="LC" and [Part Size]<7) then 2

          else if ([Part Type]="LC" and [Part Size]>13.38) then 2

             else 0

I have two part types, LC and TC.  I have six sizes.  If the size is less than 7 or more than 13.38 i want a returned value of 2. if the size is in between 7 and 13.38 I want a returned value of 0.  I used multiple lines for clarity here but the formula is just ran as a sentence in the Custom Column Formula box.

Hi @Anonymous,

You can add a custom column with following formula:

#"Added Custom" = Table.AddColumn(#"Previous Step", "Custom", each if [Part Size]>=7 and [Part Size]<=13.38 then 0 else if [Part Type]="TC" or [Part Type]="LC" then 2 else 0)

Hi @Anonymous

what is the error?

Actually, your question helped me think through why is it an error. My size was data typed as text, not a number.  Thank you!

My column just says "Error".  Any part number that is not TC and LC returns zero but any part number that is TC or LC returns "Error", regardless of size.  Thanks for taking a look...I thought my logic was okay but I'm missing something.
