for loop

Recommended Posts

I have this script that asks the user their name and email address and age and stuff and it checks to see what their age is and outputs a message depending on what age bracket they belong to.  I am trying to make a for loop that uses the value the user submitted for their age and output the range of numbers from the users age to 1000 by 3s, i know how the basic for loop works, but i don't know how to do one where you are using a variable for i. if that makes sense. Heres the code that i have.

test1.html
