White box not appearing on Thank You page

As per a different thread, I have injected the following CSS in my form:

#stage {

    background : #FFFFFF!important;

}

This was supposed to give my thank you page a white background for the textbox. For some reason it keeps reverting to a smoky grey transparent textbox even with this CSS code. How can I fix this?

Thank you!

Could you try placing a space between #FFFFFF and !important as shown below?

#stage {

    background : #FFFFFF !important;

}

If you are referring to something different or need any further assistance, please let us know. We will be happy to assist. 

Thank you for your reply. I tried adding a space and got the same result. I also tried Icopying your exact text there and replaced the old text, and I STILL get the same result. Is it possible that this code is conflicting with some other code in my form? Thank you for your help.

I just checked you Thank You Page, and it is showing the white background:

Could you check again? Perhaps try clearing browsers cache, or use another browser.
