in reply to Perl script hyperlinks not getting displayed in browser

...$value = "< a href=\"http://www.xyz.com\">7231-R</a>"; ...

...displaying $value in the other column of the table. Here, i should also be getting a 7231-R with hyperlink if the if condition is true, but i'm only getting the text 7231-R without the hyperlink. What could be the problem?

Either your browser does not like the blank in
< a
 ^
or you are overwriting $value elsewhere between calculation and presentation/printing,
my guess.


Update:

if($astatus eq "PASS" && $kstatus eq "PASS"){

Unrelated, but otherwise relevant...
you can say "AND" as && (strong precedence) and as and (weak precedence).

Your line will probably do what you meant to do when you use parentheses to remedy &&'s strong precedence as

if( ($astatus eq "PASS") && ($kstatus eq "PASS") ){

or even better with the operator and as

if( $astatus eq "PASS" and $kstatus eq "PASS" ){

    While  && has higher precedence than the  and operator, both have lower precedence than the comparison operators. In this case, parenthesization of expression terms is redundant; there will be no effect on the evaluation of the expression. See perlop.

    Such redundant parenthesization is often suggested as a documentary measure to clarify precedence for future maintainers, a practice I tend to endorse.
