Calculate % between two galleries

[Dorinda]

I have an app where I have two galleries on the screen.

The first gallery displays the hours required and the second gallery is hours completed.

I need to calculate the percentage based of the label in gallery3/gallery2,  when I do this I get the same percentage across the whole gallery 

The third gallery is where I am calculating the %, is it possible to have it do this?  So each column shows it own calculation?

Here is the code I tried for the % showing.

Text(Label5.Text/Label3.Text *100,"0%")
