Hi Everyone
I am thinking about using the Percentage Calculator
http://www.javascriptkit.com/script/script2/percentage.shtml


<SCRIPT language=JavaScript>

function perc1() {
a = document.form1.a.value/100;
b = a*document.form1.b.value;
document.form1.total1.value = b
}
function perc2() {
a = document.form1.c.value;
b = document.form1.d.value;
c = a/b;
d = c*100;
document.form1.total2.value = d
}
//-->
</SCRIPT>

<FORM name=form1>
<TABLE cellSpacing=1 cellPadding=1 border=1>
<TBODY>
<TR>
<TD align=middle colSpan=3><B><FONT size=4>Percentage Calculator</FONT></B>
</TD>
<TR>
<TD>What is <INPUT size=5 name=a> % of <INPUT size=5 name=b>?</TD>
<TD>Answer: <INPUT maxLength=40 size=5 name=total1></TD>
<TD><INPUT onclick=perc1() type=button value=Calculate></TD>
<TR>
<TD><INPUT size=5 name=c> is what percent of <INPUT size=5
name=d>?</TD>
<TD>Answer: <INPUT size=5 name=total2> %</TD>
<TD><INPUT onclick=perc2() type=button value=Calculate></TD>
<TR>
<TD align=middle
colSpan=3><INPUT type=reset value=Reset></TD></TR></TBODY></TABLE></FORM>
Is there any way to add a drop down value menu instead of typing in the numbers ?
Been a bit of a head scratcher for me so far :rolleyes:

You can always do that but do you only want whole numbers and up to what number in each field?

This will show you how you can go about it.

<FORM name=form1>
<TABLE cellSpacing=1 cellPadding=1 border=1>
<TBODY>
<TR>
<TD align=middle colSpan=3><B><FONT size=4>Percentage Calculator</FONT></B>
</TD>
<TR>
<TD>What is
<script language="javascript">
document.write("<select name=a>");
var i=1;
for (i=1;i<=100;i++)
{
document.write("<option value="+i+">"+i+"</option>");
}
</script>
</select>
% of <INPUT size=5 name=b>?</TD>

Sorry should have been more clear :thumbsup:
I am trying to figure out how to add a text drop down menu and the number which is associated to the text.
Does that make sense :confused:

You will have fun doing the arrays if this is what you want.

<TD>What is
<script language="javascript">
var iNumber=["Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"];
document.write("<select name=a>");
var i=0;
for (i=0;i<=10;i++)
{
document.write("<option value="+i+">"+iNumber[i]+"</option>");
}
</script>
</select>
% of <INPUT size=5 name=b>?</TD>

I am going to be a pain here...
Not quite what I had in mind ( but very close ), but you do your your stuff jimhill:thumbsup:
I would like something like this added..

<option value=2926>************text**********</option>

So the idea is to replace both boxes with this drop down menu style to give a overall percentage.
