I have 2 textfields…  
They have to be related to each other so when I change the data in one of them, the other changes too (not identically… calculations and stuff)

And when I change the second one the, first one has to change accordingly… like a 2-way thing

Has that something to do with listeners mby? Never used them b4 😑
