html Countdown clock size help

[Dave33]

Well I upgraded from ver. 6 to 7. I had custom html script for a countdown clock on my home page that worked fine in ver 6 but when I installed 7 the clock disappeared and only the script was showing. Well I figured out how to correct but the clock is smaller. I tried increasing the font size in the script advisor but it still shows up the same size. Anyone have any suggestions? Thanks.
