Vlookup in Textbox - Step By Step

[robert_mika]

Playing recently with many functions I have found out a way to get a value from a table  based on two fields

This solution will work like Excel INDEX/MATCH/MATCH with hard coded vertical dimension and dynamic horizontal dimension.

Very useful when you have  large data set but want to return only one value per category

Data Model

(Copy and Pasted below code into Edit Script window and reload)

t1:

Load * inline [

Helptext, Name, City, Salary ,Sales

Block, Bob, Warsaw, 100, 25

Color, John Doe, Budapest, 200, 358

Topics, Jenny, London, 300, 400

Font, Curt, Cair, 400, 800

Data ,Martin, Madrit, 500, 1500

Group ,Mirek, Mins, 600, 200

Total ,Stan ,Utah, 700, 158

]

;

t2:

load * inline [

Category

Helptext

Name

City,

Salary,

Sales

]

First table is our Data Table the second works as Headers of the dimensions.

Create two ListBoxes:

'Category' and 'Name'

create Textobject:

and add this expression into Text window:

=if( (GetSelectedCount(Category)+ GetSelectedCount(Name))<2
,'Please choose  value from two fields',fieldvalue(GetFieldSelections(Category)
,FieldIndex( 'Name', GetFieldSelections(Name))))

Press 'OK'

Your result should be similar to this:

What's does the formula do:

GetFieldSelections(Name) - is returning value (Name) from the Name field    'Jenny'

Let say we have choose Jenny

FieldIndex( 'Name', GetFieldSelections(Name))                     will return position of Jenny in the Name field

                         =

FieldIndex( 'Name', GetFieldSelections(Jenny)) = 3

GetFieldSelections(Category) this will return value from Category Field ='City'

fieldvalue(GetFieldSelections(Category) ,FieldIndex( 'Name', GetFieldSelections(Name)))

                                                                         =

fieldvalue(GetFieldSelections('City') ,FieldIndex( 'Name', GetFieldSelections('Jenny')))

                                                                     =

                                                                  London

which we can check in straight table:

The rest of the code is a wrapper which will ensure that only when value from two fields are choosen the result will be displayed.

for simplification:

=IF((GetSelectedCount(Category)+ GetSelectedCount(Name))<2,'Please select Category and Name',$(=Category))

HaimantaDawar

for pointing that this expression works only with unique values

For multiple values use:

sergey.makA8

=IF((GetSelectedCount(Category)+ GetSelectedCount(Name))<2,'Please select Category and Name',Concat(DISTINCT $(=Category),', '))

[SergeyMak]

Very interesting, but

I think it's easier just use the following expression

=IF(isNull(City),'Please select Category and Name',City)

If you don't need message 'Please select Category and Name'

= City

would be enough

The idea here is to have dynamic Category field.

Your solution works only when the Category is 'City'

[SergeyMak]

What do you think about the following expression for the textbox?

=IF(isNull($(=Category)),'Please select Category and Name',$(=Category))

[robert_mika]

Does it work for you?

[SergeyMak]

Almost...

It works if you modify it a bit, but still a bit simplier

=IF((GetSelectedCount(Category)+ GetSelectedCount(Name))<2,'Please select Category and Name',$(=Category))

[robert_mika]

Good one.

It is simpler.

It is not working if my inputs are repeated. Eg. for city if I have same city name for two or more persons then only for the 1st person its showing

[robert_mika]

Hi Dawar,

Thank you for your input.

This has not been designed to work on multiple values - for that we would probably need a custom function in VBS or JS.

I will add this comment to the docs.

Hi Haimanta,

Try this expression for a textbox

=IF((GetSelectedCount(Category)+ GetSelectedCount(Name))<2,'Please select Category and Name',Concat(DISTINCT $(=Category),', '))

It's getting more complicated

[#11]

Sergey,

Its working smooth! But do you mind elaborating this part  "Concat(DISTINCT $(=Category)" a bit
