Calculating Current Through Compensation Winding in Cascade Voltage Transformer

Got cascade voltage transformer made from two completely identical units.
On secondary winding, load takes I2=1A
Number of compensation and secondary windings is equal.
I need to find current trough compensation winding Ic
.
θ1 = θ2
--> θ1 = I1N1 + IcNc - I2N2

--> θ2 = I1N1 - IcNc

--> I2N2 = 2IcNc

--> Nc = N2

--> Ic = I2 /2

--> Ic = 0.5 AI did it like this and get feedback that this is wrong without explanation. So, I would be grateful if someone can explain me what is wrong here. I can post scheme if needed.
Thanks in advance.

Can you post a diagram labelling things? And what is theta?

I found this is correct solution, so no need to torture you any moore.

*Theta is electrical flow. If you are interested, I'll sent you sheme.
