Code: Show/Hide

win.value=""
lose = form.lose
lose.value=""

this is the problem you should set them to 0 not ""

tried using 0, same thing

is it treating yours as a string or something?
O_o"

Code: Show/Hide

p=1/(1+10^(-(y-t)/400))
w=y+(50*(1-p))
l=y+(50*(0-p))

im pretty sure the problems somewhere in there

like its doing 150+(20*5) as 150100 or something

<input class="form" type="text" id="yours"
would that kill it?

Wild guess here, but I'm assuming you are using javascript. Doing + like that in a loosely typed language will result in the language guessing what data type it is. Since the user input is a string (there is not input type=integer), it is going with a string for '150'. Thus it concatenates the string and the value of (20*5) which it takes as integers, making the '150' + '100' be '150100'.

Look up how to force a variable to be casted as a specific data type, and force the user input into be numeric, be it integers (whole numbers) or floating points (has decimals).

i expanded it into

Code: Show/Hide

a=y-t
b= (-a)/400
c=1+pow(10,b)
p=1/c
w=y+(50*(1-p))
l=y+(50*(0-p))

but then it says object expected on the pow() line
