Set Variables after a ForAll

Hi everyone,

I am having trouble with reading a NFC and then setting some variables. I have a ForAll as shown in the code that makes the

Patch only possible if it's the right NFC tag. The problem here is that I want to show a popup when the tag has been scanned but it doesn't allow me to do so in the ForAll function.

With(ReadNFC(),
 Set(id, Coalesce(Identifier, "No ID"));
 ForAll(NDEFRecords, 
 If(Coalesce(Text, URI) = "SWELL",
 ForAll(NDEFRecords, Patch('Controlo de Ponto', Defaults('Controlo de Ponto'), {'Entrada/Saída': "ENTRADA", Title: User().FullName, Email: User().Email, 'Dia e Hora': Now()})); 
)));
Set(varDisableButton, false);
Set(PP3, false);
Set(PP1, true);
Set(T1, true);

Do you have any suggestions for me so I can fix this? Thank you in advance!

Hey Rui_Couto,
Looks like you're wrestling with the ForAll function and trying to set variables after scanning an NFC tag. Handling stuff inside ForAll can be a bit tricky. Here's a tweak to your code to get that popup showing:
With( ReadNFC(), Set(id, Coalesce(Identifier, "No ID")); If( !IsBlank( Filter( NDEFRecords, Coalesce(Text, URI) = "SWELL" ) ), Patch( 'Controlo de Ponto', Defaults('Controlo de Ponto'), { 'Entrada/Saída': "ENTRADA", Title: User().FullName, Email: User().Email, 'Dia e Hora': Now() } ) ) ); Set(varDisableButton, false); Set(PP3, false); Set(PP1, true); Set(T1, true);
I added a condition around the Patch inside the ForAll loop to check if there's a match for "SWELL" in the NDEFRecords before doing the patch. This way, it won't mess up your flow.
Give it a whirl, and let me know if the popup decides to make an appearance! 🌟

Unfortunately this didn't work... I used a NFC tag without SWELL text on it and it worked... I want to read that specific tag. But thanks anyways!
