Can I put the Name and Email field in 1 line?

It is possible to align 2 fields in 1 row. You just need to use the "Shrink" function. 

Select the field first and then right click it. After that choose the "Shrink" option. You need to do the same thing with the other field. Here's a screen capture:

Hope that helps. Thank you.

for some reason my field

User 1 Email

does not get shrinked enough to accommodate field

User 2 Email

I suggest you change the Label Alignment of the field to "Top". Just select the field and then click the "Properties" button. After that, choose "Top" in the Label Alignment option.

superb! thank you!

I added the name for the 2st two fields and they do not show correct in the published form - can you please take a look?

If that's the case, then we can just change the width of the form to 900px. Please inject this custom CSS code:

.form-all {
width: 900px !important;
}
