Hi,

I need some help i this is simple but my php knowledge is too limited.
what i need is a 3 dropdown options to make a math calculation between them.

for example what i need to do is what is in this page:
example page (http://servers.internet-radio.org.uk/tools/bandwidth/)

and use it in a wordpress page, could be a input method so you get the result as you type the information in that 3 spaces.

Any help?

php is server side , to get instant as you type , you will need clientside like javscript
