宽度和长度价格计算器帮助（添加选项）使用javascript / jquery

Question

Hello Everyone ,

I have a problem with my price calculator when i've tryed to add options

( Js fiddle here = http://jsfiddle.net/wemdragon/hXydV/ )

What i'm trying to do is where it says:

var firstoption=$('select#myselect') i would like the options value turned into a price value like : option value (Which is 1 ) = 20.00 but can't seem to do it.

If anyone could nicely help me and tell me what i'm doing wrong with this, i'l really appreciate it.

You should probably give the <option> the values you want, then just use:

var firstOption = +$('select#myselect').val();

jQuery val() grabs the selected value, and the + converts the string value (like "20" ) to a numeric.
