Parse Error

[dhakim1996]

Hi, could any one assist why I am getting this error. 

I have changed the column No. to string. Here's the expressions used:

IIF([Row-1:No.]+1=[No.],[Row-1:New Field] , [Row-1:New Field]+1)

I am doing sequential check. 

Thank you.

Hey @dhakim1996,

You cant add one +1 to text data (string data) you can only do that to numeric data. Ether convert it back to a number before this or you can use the to Number function like this: 

IIF(toNumber([Row-1:No.])+1=toNumber([No.]),[Row-1:New Field] , [Row-1:New Field]+1)

Hi @IraWatt 

Thank you for the quick reply! It works now however it is not returning the desired results as this was what I wanted:

No.	NewField
20220001	-
20220002	1
20220004	2
20220006	2

The new field is a sequential testing that would return the difference between the previous row. Anything that is more than 1 I would like to flag it out.

Hey @dhakim1996, I think I get what you want to achieve. Would you be able to give the result you wanted in the table above?

[dhakim1996]

Hi @IraWatt sorry I dont get what you mean by giving the results I wanted? 😅

[IraWatt]

@dhakim1996 ah sorry I thought the table you have above was the results you got from your multi row Tool. I take it this is the results you where wanting to get out of the tool:

No.	NewField
20220001	-
20220002	1
20220004	2
20220006	2

Are you just calculating the difference between the two rows here? You said anything that is more than 1 I would like to flag it out, what does this mean? The first two rows are less then 1 difference and I don't see the difference between them and the other rows?

[dhakim1996]

Yes @IraWatt I would to get a difference between two rows. Any difference of more than 1 between two rows I would like to subsequently filter out. However, how do I calculate the difference between 2 rows?

[IraWatt · Accepted solution]

@dhakim1996 I would use a formula like this:

IF [Row-1:No.] = NULL() THEN NULL() ELSE

toNumber([No.])-toNumber([Row-1:No.]) 

ENDIF

The first bit checks that the row above exists if it doesn't it just fills the value with NULL else minus the current row with the one above.
