Hi Masters,

I'm stuck at a code that gives ERROR! I'm not able to figure out why these error is reported. To my understanding I'm defining a local variable and assigning hash table values to my locally defined variable. Then I'm trying to print by adding these local variable to pre-defined array elements (DIN_SETUP_RISE[0] .... ). Please help me!!! Thanks.

    (W uninitialized) An undefined value was used as if it were alread
+y
    defined.  It was interpreted as a "" or a 0, but maybe it was a mi
+stake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl tells you what ope
+ration
    you used the undefined value in.  Note, however, that perl optimiz
+es your
    program and the operation displayed in the warning may not necessa
+rily
    appear literally in your program.  For example, "that $foo" is
    usually optimized into "that " . $foo, and the warning will refer 
+to
    the concatenation (.) operator, even though there is no . in your
    program.
