Don't want "NULL" in form field



I'm passing parameters to a DataPage form via URL from an external source. Some of the parameters are empty. These show NULL in the text fields. I would like to have these fields just empty. How can I do that?

To Datapage:

I have this script but not sure if this is the way to go, or how to implement it ($_Get)???:

function getQuerystring(key, default_)


if (default_==null) default_="";

key = key.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");

var regex = new RegExp("[\\?&]"+key+"=([^]*)");

var qs = regex.exec(window.location.href);

if(qs == null)

return default_;


return qs[1];

Snippets of JavaScript, HTML or CSS can be added in HTML Blocks (https://howto.caspio.com/datapages/datapage-components/html-blocks/) & Header and Footer (https://howto.caspio.com/datapages/datapage-components/datapage-header-and-footer/).

Thanks Bahar!

It's not on your side...the program I'm passing the variable from inserts the NULL...

Can a script like the one I posted above be implemented via an HTML Block?
