<br>
<input type="text" size="10" name="best_propane_pressure" readonly>
</form>
</html>

thats the what i began with, i know that my onchange="" and my onclick="" are all wrong, but i dont know how to fix it. if some1 could fix the first few as an example for me, i *may* be able to figure the rest out.

thanks for at least reading my post, i really hope some1 can help.

*cough* Wrong forum. You may also want to describe your problem in specific, as just blankly saying they "don't work" is a bit general.

Having trouble with your form in IE?
thats the 1st thing i saw
or should be in Client Side Scripting place?
i'm an idiot, move this if any mod wanna.

bw, i dont know any javascript, i dont know to make a box display the result of a simple calculation: doc.form.input.value + doc.form.input2.value
