Using Variables to choose Column in Gallery

[Silias]

I'm just starting out and I have some trouble with my app. At the start-up I set my "CurUser" variable to my User().Email and substitute the "@" and ".".

Afterwards I am going into a "Detail Gallery" that has a filter set to a specific item ID. Now I want to have  label that displays the Value of my current User (like ThisItem.CurUser) , but I can't get it to work as LookUp just returns the text value and most other things give me an Error.

Does anybody have an idea on how to approach this?

Hi @Silias ,

If not text value what is the value you want to compare ?

Hi @PG_WorXz10 ,

I indeed want to compare two text values. The name of the Column and my Variable, but for some reason the LookUp and likes Function don't like using a Variable for the Column Name.

Hey! ThisItem.CurUser does not exist.

You have CurUser.Email or CurUser.FullName

LookUp(List; Email = CurUser.Email)

This will return the item

Hi @Silias ,

CurUser=User().Email (eg: xyz@email.com)

This is a variable you can print in a lable but if you want this value in a gallery for all the items this will be CurUser.
But In case you want this value to Lookup any value from Gallery collection than you can use below formula

Lookup(DataSource, EmailColumnName=CurUser).ValueRequired
