ColdFusion Logic
Hello I am new to scripting. I decided to learn CF. And i have been asked to
make a paint calculator, that calculates the amount of paint u need to use
based on the area ur gonna paint. Well i created a form where u can selct
diferent types of paints, and then when u select ur paint u enter the base and
the hight and a submit button to calculate it. Well, i have been having some
problems with the code, cuz when i select another painting category after
calculating the amount of paint, the form stays with the values. i need to make
them so that when i select another type, the form resets. Well if annyone can
help me, that would be great.
Thanks,
Coto
Here is the code:

<cfif IsDefined("URL.Submit")>
<cfset multiplica = URL.base * URL.altura>
<cfset resultado = multiplica / rendimiento>

jdeline #2 Re: ColdFusion Logic
Welcome to the world of scripting.
For starters, replace that initial CFIF / CFELSEIF piece of code with
CFSWITCH / CFCASE Check out
[url]http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/tags-c10.htm#wp1103819[/url]
for the detalis. Second, when copying code into a posting on these forums, use
the "Attach Code" button at the bottom of the screen. And indent, indent,
indent if you want people to read your code.
I'll try to address your other issues later today.
