Function addvalues help
Can someone please advise, been looking for a code on the internet to convert minutes to hours in human time and not decimal. Searched for a long time and finally have came accross a script that does what I want but have had to make a few alterations to make it look the way i want..but the only problem is that when I click calculate it keeps adding the total. Could someone please take a look at the script and show me a way to just calculate once and not keep adding up (so..when you hit calculate it gives one answer, but the answer wont change until you hit reset) I know this is basic stuff to most coders, but I just cant do it. Thanks for any help...Heres the code I have.

var the_minutes = parseInt(myForm.total_time_hidden.value.substring(myForm.total_time_hidden.value.indexOf(":")+1,myForm.total_time_hidden.value.lastIndexOf(":")));
