Posted on by Feenix

I have some code that is giving a blank value. however, if I use parts of the code in a text box, it shows correctly. What am I missing?

Set(
 currentUser,
 User().Email
);
Set(
 currentRole,
 LookUp(
 UserEdit,
 'Editor Email' = currentUser,
 Role.Value
 )
)

Hi, i think your Lookup is configured wrong:
Lookup needs 2 Arguments Lookup(Datasource,Formula to evaluate right record)
Your Formula has 3 Arguments.
Also, Lookup returns the datatype "record" which means some kind of a dictionary. In fact, it will return the whole row from your datasource, in ehich the condition matches.
One solution I can imagine is:
Set( currentRole, LookUp( UserEdit, 'Editor Email' = currentUser ).value )

Hi,

Thanks for responding. copying and pasting your code returns an error, but...

If I do this:

Set( currentRole, LookUp( UserEdit, 'Editor Email' = currentUser ).Role

and change the text box to currentRole.Value, I get a blank response.

If I do this:

Set( currentRole, LookUp( UserEdit, 'Editor Email' = currentUser ).Role.Value

and change the text box to currentRole, it gives a blank result.

Ultimately, I would like to set the users role when they open the app so that I can use it to dictate what they see without having to check their role multiple times. I feel like this would create multiple connections to the sharepoint list than what is needed.

OK. Is it possible, to provide a screenshot or further details of the datasource named UserEdit? Please provide also de datatypes of the collumns.
But is seems you make some progress. If the Lookup works, you only have to get the right values from the response.
You can also debug the response of the lookup by creating a variable named currentRoleRecord:
Set( currentRoleRecord, LookUp( UserEdit, 'Editor Email' = currentUser )
I would set this code to the OnSelect of a button, so you can easy trigger it.
After that, you can check the variables pane on the left and explore the global variable you just created.

Im not sure what happened yesterday, but today the code below is working.

Set( currentRole, LookUp( UserEdit, 'Editor Email' = currentUser ).Role )

While messing around with it this morning, I ran the "Run Onstart" for the app and the value showed. I was thinking I did that yesterday but maybe not. Its working today. Thank you @Anonymous for the help with the .value I was missing from the end of the code.

Oh, nice to hear.

Actually, adding a .value is a common practice you have to do sometimes in powerapps 😂
