You did? How did that work out for you.

Yeah, in a form if you want the user to choose a number like that you can 
use an html select / option, or a set of radio buttons, or you could use 
a text input and let the user enter a number, but they might enter a 
number outside your range.

This sounds more like a javascript thing than a php thing, you probably 
don't want to submit your form to the server each time the user changes 
their option.

Not quite sure what a nog is.

Well you'd use an appropriate javascript function to get the value from 
the input type that you were using, making sure that you did any needed 
conversions to numeric data if it started life as a string value, and 
then do the relevant multiplication and display it in a suitable output 
location.

> Any help is greatly appreciated

You're welcome.

xp and fu set, this sounds like primarily a js issue, not a php one
