returnURL with parameters

returnURL with parameters

Hi,

We need to set a returnURL with a query string.
When I do this the system gets stuck on a blank page while submitting the form.

Here is the code as example:

<form id="dc-form" class="dc-form" action=" https://crm.zoho.com/crm/WebToLeadForm" method="POST" name="WebToLeadsxxxxx" onsubmit="return check_form(this)" _lpchecked="1">
<div class="dc-form-fields">
<input name="xnQsjsdp" type="hidden" value="xxxxx">
<input id="zc_gad" name="zc_gad" type="hidden" value="">
<input name="xmIwtLD" type="hidden" value="xxxxxx">
<input name="actionType" type="hidden" value="xxxxxx=">
<input style="display: none;" name=" returnURL" type="text" value="http://www.inspirationgroup.biz/ty/?testparam=testval&testparm2=val2">
<input id="Lead-Source" name="Lead Source" type="hidden" value="xxxxx">
<input id="name" name="Last Name" type="text" placeholder="שם">
<input id="mail" name="Email" type="text" placeholder="דואר אלקטרוני">
<input id="phone" name="Phone" type="tel" placeholder="מספר טלפון">
<input class="dc-form-submit" id="dc-form-submit" value="שלח >>" type="submit">
</div>
</form>
