Reposition error box – css not working

Hi
You have listed on your support site information on how to change content of the error box but not the position.

I know the variables to change, but it is not working. Here is what I found and pasted in css:

.widget_wysija_cont .formError {
opacity: 0.87;
position: absolute;
top: 2725.57px;
left: 508.2px;
margin-top: 0px;
}

I changed the top and left variables pixels. Is there something I’m missing? Right now the error message is over the button as I have made the input boxes inline – can you help? Thanks
