Re: best way to test for the existence of a parameter in a url

texte = Try this:[formvariables name=[url]--eqskudatarq[/url]][if [url][value][/url]!][then] ... --eqskudatarq exists and has a non-blank value ... [/then][/if][/formvariables] Note that just saying [formvariables]...[/formvariables] performs a loop through all of the form variables passed in. Within the [formvariables] loop, [name] is the name of the formvariable for the current iteration of the loop, and [value] is its value, while [index] tells you which iteration you are on.I prefer the formvariables method over the other methods people have suggested, because it distinguishes between formvariables passed in to the page and other variables (text, math, db fields) that may have been created with the same name.- brian On Tuesday, April 29, 2003, at 10:59 AM, Lucas Rockwell wrote:> Howard, > > Thanks.
