i have this code where it computes for the time entered by the user.
it doesn't have yet the limitations or the conditions regarding the time to be entered .
it successfully computes for the time and the hour increases based on the minutes, but the problem is when you entered "9" for the hour it doesn't add to the total but the rest is fine.. anyone can help ?
so here it is:
<html>
<FORM>
<table name="tblSamp" border="1">
<tr><th>Time</th>
<td><input type="text" name="alpha" value="" onchange="addColon(this.form.alpha, this.form.total);" maxlength="5"/></td>
<td><input type="text" name="beta" value="" onchange="addColon(this.form.beta, this.form.total);" maxlength="5" /></td>
<td><input type="text" name="gamma" value="" onchange="addColon(this.form.gamma, this.form.total);" maxlength="5"/></td>
<td><input type="text" name="total" value="" readonly="readonly" /></td>
</tr>
</table>
<input type="hidden" name="displaycount" size="20">
</FORM>
<SCRIPT TYPE="text/javascript">
var hours = new Array();

//alert("cell index=" + cIndex);

if(string != "" & !isNaN(string)){
if(i < 0){//if colon == 0
if(strlen < 3){//for input 12 = 12:00
//alert("for input 12 = 12:00");
hours[cIndex] = string;

string = string + ':00';

just copy the whole thing and you can try it ...
i really need help in this. i can't see where did that problem come from ..
cheers,
