Basic FB edit question

I've created a simple contact form and everything seems to work ok. Now I need to change the color of the form "labels" from the default #b6b6b6 to black #000000 . I use FormBuilder to make the change but it doesn't show up when I check in the file to the live site?

I guess I don't understand the basics of how to use the webassist tools. Here's a few simple questions I could use answers to:

1) When I make changes, like above, using FB what files do I have to check back in to see the changes. I assume a css file is being updated to change the color of the labels to black.

2) Do I have to check out files other than the contact form before I make updates?

1) if the only change being made is to the CSS, the CSS file for the form is in the webassist/forms folder. Dreamweaver will show the names of linked files along the top to help you pinpoint the exact files, if in double, upload the entire webassist folder.

2) Yes, when making CSS Changes, form builder needs to be able to edit the linked CSS Files, if checkout / Checkin is enabled, form builder wont be able to make those changes if the CSS file is not checked out.
