Comlpex if statement not working in tibasic

I'm making a game that requires some complex if statements, here is the code that doesn't work

If K=25 and not(Y=1) and not([A](X,Y-1)=1)
Then
... Other Code ...
End

but it works when I do

If K=25 and not(Y=1)
Then
If not([A](X,Y-1)=1)
Then
.. Other Code ..
End
End

What's the problem?

A problem with a condition such as not(Y=1) and not([A](X,Y-1)=1) (by the way you can use the ≠ operator instead of combining not( with =) is that both sides of the and in TI-BASIC are always evaluated (in contrast to how it works in many other languages). That means that if Y is actually 1, then the expression on the right hand side is still evaluated but it fails with an INVALID DIM error. So, unfortunately, conditions like that must be split up.
