hey, hey
what's up everyone?
i'm new to the world of javascript and i've encountered some problems while working on a customer fill-out form.
i'm hoping someone here could help me out... please...
here are my questions:
1. how do i connect a .js file (containing javaScript functions) to an html file that uses it's functions (a css file also needs to be connected to the same html files)?
2. how do i turn decimals from something like this, 2.23232423213, to something like this, 2.23?
3. i need to check that certain field within the customer form are filled in in a certain way... to me, the expressions i've used seem like they should work, but my computer disagrees. can anyone give me some suggestions on what i'm doing worng, or if i'm right on any of these?
