Hello Folks,

I have referred many useful posts in this forum but still I couldn't figure out what I am doing wrong to make this formula working.

I have two SharePoint lists where I want to "add Columns" in Data Table as per my Excel Vlookup formula.

List1: BuildingDetails

Building Name	Urban/Rural	Length	Area (m2)	Polymer/Non-Polymer
SutherLand	Urban	1230	11300.625	Polymer

List2: EmulsionDetails

Poly/Non-Poly	Emulsion
Polymer	0.73
Non-Polymer	0.67

In my PowerApp: I have added the data table and it refers the following formula:

AddColumns(BuildingDetails,"LookupTest",LookUp(EmulsionDetails,'Poly/Non-Poly'=BuildingDetails[@'Polymer/Non-Polymer'],Emulsion)

The above formula is producing `Invalid Argument Type`.

Question 1: Kindly advise what I am doing wrong ? Or is there any other way to achieve this.

Question no 2: When referring column name do I need to include the quotes in formula bar for SharePoint list - What is the best way to pick up correct column name ?

Please help.

Hi @ragavanrajan ,

Assuming these are both Text (Single line of text) fields, the below should work.

AddColumns( BuildingDetails, "LookupTest", LookUp( EmulsionDetails, 'Poly/Non-Poly'='Polymer/Non-Polymer', ).Emulsion )

Also when you are typing the valid field names should come up underneath.

Hi @WarrenBelz Thanks for your reply. I am terribly sorry for not mentioning my field details. In the "EmulsionDetails" Table - Poly/Non-Poly field is a Choice field.

I have many more list which I wanted to do with a same format. I need to reference Choice Fields. Could you please let me know how can we achieve this? Thank you.

Thanks @ragavanrajan ,

This should work - I assume 'Polymer/Non-Polymer' is a Text field

AddColumns( BuildingDetails, "LookupTest", LookUp( EmulsionDetails, 'Poly/Non-Poly'.Value='Polymer/Non-Polymer', ).Emulsion )
