In FireFox it works perfectly. In Chrome, the "Next" button remains hidden even after the area is calculated.
It seems to me the Javascrtpt on line 128 does not work in Chrome.
Does that have to be different?
If you want to see it live, go to www.rkassoc.org/Lakos
Select United States, Any State & Basin Cleaning. Enter values for Length, Width & Depth (integers). Click elsewhere on the page; in FireFox, the Next button is visible in FireFox, not Chrome.
How can I make it work in both?
