Calculing porcentage

[PedroBrandt]

Hi guys, i'm starting in powerapps, so maybe is newbie question....

I'm making a basic register form to save all sales in the company, but we need to calculate a final value with porcentage. We have the first value in a datacard,  another datacard with porcentage value and the final value calculing 1100 / 10 showing in a label

After all, the datacard "Final" will get "Inicial value" + "Label" and show in "Final".

In the "Final" default propety (Value(DataCardValue3.Text) + Value(Label3.Text))

But i receive this error ""

I need to put this values in a datacard, beacause i will save in a list on sharepoint.

If anyone could help me in this situation i will be thankfull!!!

Can you please show your code for the Default property in DataCard3 and also for DataCard8?  One of those is referring to your label and causing a circular reference.

I don't have any code in the Default property.

Please share the code you have written for the property with a circular reference. We can troubleshoot from there.
