What’s the function of the below? ;

Any inputs on “GRT”, depends on the number of the unit(1, 2, 3 etc..), the results shows on “Amount”.

@HaganeNoKokoroJul 26.2004 — well, for starters, the field for unit probably needs an id before we can use its value. I am going to pretend that its id='unit'

document.getElementById('amount1').value=Number(document.getElementById('a'))*Number(document.getElementById('unit'));

assuming, of course, you want the product of the two values.

this should go in your calcValue function (probably instead of setting amount1's value to (a's value*0))

@oceanmaidauthorJul 26.2004 — After I did the changes as above, it's not working...?

@HaganeNoKokoroJul 26.2004 — there is still a line, later in your calcValue() function:

document.getElementById('amount1').value = Number(getEl('a').value) * 0;

remove it because it is setting the value of amount1 to 0 no matter what.

oh, and oops the code i should have given you before was:

document.getElementById('amount1').value=Number(document.getElementById('a').value)*Number(document.getElementById('unit').value);

@oceanmaidauthorJul 26.2004 — Could you insert for me the functions and send me the entire script?

Gee, thanks..?

BTW, how could it be like the below? ;

document.getElementById('amount1').value = Number(getEl('a').value) * 0;

Isn't anything times 0=0

Man, this is so confusing...Plase help..

@HaganeNoKokoroJul 26.2004 — <i>
</i>function calcValue(){
document.getElementById('j').value = Number(getEl('a').value) / 100 * 2.2;

/* This is the line I added */
document.getElementById('amount1').value=Number(document.getElementById('a').value)*Number(document.getElementById('unit').value);

dues=document.getElementById('k');
val=Number(getEl('a').value);
if(val&gt;40000)dues.value=175
else if(val&gt;20000)dues.value=140
else if(val&gt;10000)dues.value=105
else if(val&gt;5000)dues.value=80
else if(val&gt;2000)dues.value=60
else if(val&gt;1000)dues.value=40
else if(val&gt;75)dues.value=25
else if(val&lt;=75)dues.value=0//do not know, if you need this

/* this is the line i removed */
//document.getElementById('amount1').value = Number(getEl('a').value) * 0;

document.getElementById('total').value = Number(getEl('b').value) + Number(getEl('c').value) + Number(getEl('d').value) + Number(getEl('e').value) + Number(getEl('f').value) + Number(getEl('g').value) + Number(getEl('g').value) + Number(getEl('i').value) + Number(getEl('j').value) + Number(getEl('k').value) + Number(getEl('l').value);
}


the line:

document.getElementById('amount1').value = Number(getEl('a').value) * 0;

was already in your original code, that's why i said remove it

@HaganeNoKokoroJul 26.2004 — I think I found it!

you have a line:

bindEvents(getEl('a'), getEl('b'), getEl('c'), getEl('d'), getEl('e'), getEl('f'), getEl('g'), getEl('h'), getEl('i'), getEl('j'), getEl('k'), getEl('l'));

change it to:

bindEvents(getEl('a'), getEl('b'), getEl('c'), getEl('d'), getEl('e'), getEl('f'), getEl('g'), getEl('h'), getEl('i'), getEl('j'), getEl('k'), getEl('l'), getEl('unit'));

sorry it took so long to figure out, i'm used to handling events a little differently.
