Update the value of a text field

[nalbiso]

Hi,

Can anyone provide me with a script on how to update the value of one text field based on the value of another text field? I would like to update the value of a text field on my form called "FutureHoursNeeded" based on the value inputted in another text field on my form called "PercentCompleted".

It should perform an operation to check
if (document.editProj.PercentCompleted.value=="100&quot {

and if it does then a value of 0 should be written to FutureHoursNeeded.

Any help is greatly appreciated!

What if the project is only half-finished?

<form name=projectReport>

<input type=text name=&quot;PercentCompleted&quot; onChange=&quot;calculateHoursNeeded()&quot; value=&quot;0&quot;> 
<input type=text name=&quot;FutureHoursNeeded&quot;> 

</form>



<script>
function calculateHoursNeeded(){
   var pDone = document.projectReport.PercentCompleted.value;
   var hoursTotal = 40;  //This could be picked up from a text field in the same form.
   
   hoursNeeded = hoursTotal * (1-(pDone/100));
   
   document.projectReport.FutureHoursNeeded.value = hoursNeeded;
}
</script>

Hi,

Thanks, but I only need this script to change future hours to 0 if percent completed is equal to 100. Future hours is only the visitor's estimate on how much time he/she will need on a project as different visitors can work more or less than 40 hours per week on a project and therefore are not consistent.

Another field on my form already computes the total hours expended on the project.

Thanks!
