Zoho web2lead Form Problems

Zoho web2lead Form Problems

I am trying to integrate the web2form into Joomla.  I am using the plugin from Blue Flame.  The problem I am having is the Zoho form fields use "First Name" and "Last Name"  and due to the way the plugin handles the fields - cannot have a space - I am not able to get those form fields to parse and submit to Zoho.  All other fields are working and submitting data to zoho except for those two.  My developers and the Blue Flame are telling me that I need to change the form fields in order for it to work but I can't find anywhere to do that in Zoho.

Is there anywhere in Zoho I can change the "First Name" field to "firstname" or even "First_Name" to get rid of the space?


Thank yo
