Easy Math Problem

[sean_the_hacker]

I am a begginer of JavaScript and I was just writing a simple fraction to decimal conversion page; but I had a few problems.
When I added two of the variables together it does this

Say I had the fraction 1 1/2, and I tried to convert it, this is what happens:

it comes up with 10.5 as the answer, because it adds the variables, instead of adding the values of the variables.


Any sugggestions?

If im not mistaken, i think you need to use something along the lines of the val function.

like val(variable1) + val(variable2)

Just a thought, dont know if that will help or not.
