Closing lines on form dissapearing

line 1775 of your default.css file sets the form width to 580px. That's where the issue is coming from. You can reset it by adding this to the end to your theme stylesheet

body #contentbox #gform_wrapper_4 form {width:570px}

The extra padding on the inputs pushes the widths out further and ends up trimming them. Try adding this to your stylesheet

body #contentbox #gform_wrapper_4 form {width:570px; overflow:visible;}
body #contentbox #gform_wrapper_4 form input {padding:5px 0}

Where are you adding this? I don't see it being applied anywhere and the snippet should work just fine if applied correctly.

@scott74 There aren't any tutorials for pulling cost and quantities from for fields to populate estimate for FreshBooks. The problem you are having is because you are trying to use Pricing Fields with the FreshBooks Add-On. The Pricing Fields are a 1.5 feature and 1.5 is still a development release. The FreshBooks Add-On has not been updated to support the new Pricing Fields and will not be updated until 1.5 is released as a final release.

Looked at your style.css file and you have a syntax error. You didn't properly close this rule.

selections {
	background-color:#4D7DB3;
        color: #FFF;

If you'll notice, the end bracket is missing. This breaks the rules after it. Fix that up and see if it works for you.

You can refer back to the other topic you referenced and we'll address the other issue there.

Looking good for me -

Are you still not seeing it? If so, what browser and also, have you tried clearing your browser cache?

Yeah, it would help if were looking at the same form I guess. I was working on the one you originally referenced and yes, that CSS snippet was specific to that form ID. If you want it to apply to all forms, then you would use the class name for the form wrapper rather than the unique ID

body #contentbox .gform_wrapper form {width:570px; overflow:visible;}
body #contentbox .gform_wrapper form input {padding:5px 0}

This might be helpful for you as well. It's a guide to targeting specific form elements with CSS - examples to apply styles for all forms or for unique form ID's
