I want to bold and increase the font size to Arial 10 on the Total column in a constant sum table.

Kfisherk
Kindly include this in Custom CSS:
.Skin .CS .CSTotal, .Skin .CS .Total {
font-weight: bold;
font-family: Arial, sans-serif;
font-size: 14px;

}
Hope this helps!

What are the units on the 10? 10px is very small. The typical default is 16px.
Anyway, you can use a CSS style something like this:
.Skin .ChoiceStructure .DarkBG, .Skin .ChoiceStructure .DarkBG input[type=text] {
font-weight:bold;
font-family: Arial, sans-serif;
font-size: larger;
}

Thank you all for the suggestions. You are right I want to use 14px. As I am new to this can you please show me where I include the code. Here is the default Java Scrip. When I copy and paste the code provided, I get an error - invalid token. Any additional help will me much appreciated. Best, Karen

You need to include this in Custom CSS in Look and Feel.
Hope it helps!
