Question

image.png.ae2f16262d05eb8cac0be9e2da5973d3.png

CASE
WHEN Charindex('-',[@field:BoxNumber],0) >= 1 THEN
Cast((
(Cast((Right([@field:BoxNumber], (Len([@field:BoxNumber])-Charindex('-', [@field:BoxNumber])))) AS int))
-
(Cast((Left([@field:BoxNumber], Charindex('-', [@field:BoxNumber])-1)) AS int))
+1
) AS varchar)
ELSE
'1'
END

I have the above code inserted in [BoxCount] formula datatype field to get the difference of two values from a single field ([BoxNumber]) if it has dash(-) in it else it should be set to one(1). 

Below is an example. For the highlighted row, the result of the formula should be 2 - basically (35142-35141)+1.

When I checked it in the "Verify formula" button, caspio considered it as valid but when I tried saving it, caspio throws the below error.

What am I missing here?

@crionsynx I replicated your table setup and it shows me "valid formula" when I verified it. Granted I don't have any data in it. That might be the difference on our setup.

You may want to look into this forum post on how formulas are validated on Caspio for reference.

I also tried to run you formula and its not working properly. I created my own version:

CASE
WHEN Charindex('-',[@field:BoxNumber]) > 0
THEN CONVERT(INT,Left([@field:BoxNumber], Charindex('-',[@field:BoxNumber])-1)) - CONVERT(INT,right([@field:BoxNumber], (Len([@field:BoxNumber]) -Charindex('-',[@field:BoxNumber])))) +1
ELSE '1'
END

Thank you for looking into this @Wikiwi.

I think my formula is also working and I found out now the real issue. It is not because of the formula but because of the existing data in the BoxNumber field.

I have some data in the BoxNumber field that have string(alphabet) values besides the dash(-) itself.

It will fail since it is impossible to convert.
