Yield Code

[gordon]

:confused: Hi. I am trying to find a code for my web site that is not on line yet.
It is a recipe site and YIELD which means how many is a code i'm looking for.
When you click on yield it converts a recipe from 1 person to 2 or 3 or more.
EG 1 chicken breast, 1 cup rice, 1 tomato etc for 1 person. Click on yeild and it doubles the ingredients or more.
Can you help.
Many Thanks:)

This can be done with Javascript, but is better with a server-side backend. What server-side languages do you have available on your server?
