Name field with Prefix have now gone to two lines

The only thing I'd changed was the colour of the submit button. I've tried changing the height and width of the iframe code but mks no difference.

Please try increasing the Height property of you iFrame code to "800" in order for the Submit button to show:

Increasing the  height works well. Thanks. However, the Your Name line is still on two lines. I need it on one. What can I do please?

Please try injecting the following CSS code as instructed in this guide: http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

#cid_22 span.form-sub-label-container {

    width: 137px;

}

[data-type="control_fullname"] .form-sub-label-container:first-child {

margin-right: -5%;

}

#first_22{

margin-left: -50px;

width: 165px;

}

#last_22 {

  width: 165px;

  margin-left: -25px;

}

#sublabel_first{

margin-left: -47px;

}

#sublabel_last{

margin-left: -25px;

}

It should go from this:

To this:

Please inject this code instead, the previous one got a typo on it and I adjust some margins:

#cid_22 span.form-sub-label-container {

    width: 137px;

}

[data-type="control_fullname"] .form-sub-label-container:first-child {

margin-right: -5%;

}

#first_22{

margin-left: -55px;

width: 165px;

}

#last_22 {

  width: 165px;

  margin-left: -25px;

}

#sublabel_first{

margin-left: -52px;

}

#sublabel_last{

margin-left: -25px;

}

It will look better:

I'm sorry. It looked even worse. The fields were stil spread across two, only now the second line was pushed way over to the left. I've now ditched the prefix altogether, but I would still really appreciate being able to reinstate it on a single line. Any other ideas? I've also making my form wider but that doesn't help either. 

What else can I try???

I have added the following CSS to your form in order to fix the fields lining issue.

[data-type="control_fullname"] .form-sub-label-container {

    width : auto;

}

[data-type="control_fullname"] .form-sub-label-container {

    margin-right : 2% !important;

}

Thank you.

That's brilliant, Mike. MANY THANKS.
