Text Expected

Hi,

I have a field - mylist which is a multi-value field, seperated by new line.

Then I have a multi-value field - outR which does a calcualtion on the field - mylist. Both fields are text fields.

However, I get the error:

“Field ‘outR’:Incorrect data type for operator or @Function:Text Expected”.

Below is the formula:

@Transform(mylist; “x”;

@Do(

_pos := _pos + 1;

_mod := @Modulo(_pos; 5);

@If(_mod = 1;

@Do(

_min := x;

_max := x;

“-”

);

@Do(

_min := @Min(x; _min);

_max := @Max(x; _max);

@If(_mod = 0; @Text(_max - _min); “-”)

) ) ) );
