You are only looking for the key "LYPLA1", which happens to be the first element of @gl and therefore your result will show for every match of "LYPLA1", the first element of @csta, i.e. "4797974". You might wish to vary the search keys a bit to see something different.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
