Getting same number in both

why i am getting this error?

If you aren’t using any global variables in the function, please click my name and message your notebook as an attachment.

@Sanket_Yadav
You are using the global variable train_sentences inside the function seq_and_pad. Please fix it.

so what should i write there i didnt understand

Make use of function arguments when possible instead of relying on global state. Please read the function signature and instructions carefully.

if i changed train_sentences to val_sentences i get 455 in both

got ittttttttt i have done the changes that you had tell me.
