I'm trying to create a page that includes two javascript 'calories burned' type scripts on the same page. One covers calories burned while exercising, the other while working. Each uses the same script. If I run each one on separate pages, each works. But if I combine them on the same page, I get javascript errors. I've tried having both instances of the script on and having just one instance of the script with both forms.

The script used is:

Code:
 
<SCRIPT LANGUAGE="JavaScript">
<!--
function FigureBURN(form, pounds, minutes, activity) 
{
 Weight   = (pounds / 2.2)
 Time     = minutes
 activity = document.BURN.activity.options[document.BURN.activity.selectedIndex].value
 form.calcval.value = (Math.round(Weight * activity)*(Time / 60))
}
// -->
</SCRIPT>
I'll cut out most of the options in the forms to save space here. The forms used are

Code:
 
<FORM NAME="BURN">

WEIGHT (pounds)
<INPUT TYPE="TEXT" NAME="pounds" SIZE=5><br>
MINUTES WORKED:
<INPUT TYPE="TEXT" NAME="minutes" SIZE=5><BR>
WORK
<SELECT NAME="activity">
<OPTION selected value="4"> Bakery, general
<OPTION value="3.5"> Carpentry, general
</select>
<br><br>
<INPUT TYPE="BUTTON" name="calc" value="I burn" onClick="FigureBURNa(this.form,this.form.pounds.value, this.form.minutes.value,this.form.activity.value)"> <INPUT TYPE="TEXT" name="calcval" size=10> calories at work!
</FORM>
and

Code:
<FORM NAME="BURN">
WEIGHT (pounds)
<INPUT TYPE="TEXT" NAME="pounds" SIZE=5><br>
MINUTES EXERCISED 
<INPUT TYPE="TEXT" NAME="minutes" SIZE=5><BR>
EXERCISE 
<SELECT NAME="activity">
<OPTION selected value="5"> Aerobics: low impact
<OPTION value="7"> Aerobics: high impact
</select>

<BR><BR>
<INPUT TYPE="BUTTON" name="calc" value="I burn " onClick="FigureBURN(this.form,this.form.pounds.value, this.form.minutes.value,this.form.activity.value)">

 <INPUT TYPE="TEXT" name="calcval" size=10> calories at the gym.
</FORM>
Can anyone suggest a way to make this work on the same page?

thanks
