How can i use AND (&&) and OR (||) in one if statement

Hi all, please I am seeking you help, I am using the following if statement

if y~=1 &&  y~= length(Radius) && -1.1<=aa_ && aa_<=-0.98

to check for any aa_ that is -1.1<=aa_<= -0.98 and not located at the length y that is ystart<y<yend

However their was no data found even though there are around 300 aa_ that satisfy this condition.

does anyone know the reason and if the IF statement need to be fixed

Thanks, Aziz
