If you use CGI, the module helps you to override sticky values, using the "override" attribute of the field element.
I apologize for not knowing exactly what you are looking for, so that my example can be simply plugged in as-is. But, maybe it can be helpful in a general way.

$out->textfield('_variable' ,$out->param('redirect')?$ref->{'url'}:'qu
+icklog',20,-override => 1)
[download]

'_variable' is where the field value is stored.
$out is the name of the CGI object.
$out->param('redirect')?$ref->('url') is the parameter that expands to the default URL, over which I want to force changes using the form. And here comes the answer to your question (hopefully):
-override => 1 allows the default parameter to be overridden by the submitted form contents.

If you don't want to use CGI, you may still find this to be a good clue - but I don't have much experience trying to create form and field code without CGI.pm :-)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
