Dear all,
I have a javascrript that takes tree values from from a form, does some calculations and then return the value of the calculations into a window of the form. This javascript works great in netscape, but it does not work with intenet explorer. Moreover, it does not pass the calculated value to a cgi script that I am working on. The javascrirpt is at the url http://mif.dfci.harvard.edu/temp_javas.html, and the code is in the body of this e-mail
If anyone see where is the problem I will be glad to hear about. thanks in advance for any help

cheers

Dear Dave, thanks a lot for suggesting turning on error reporting in IE. Once, I do that I get a error in line 30 chanr 12 saying that object does not support this property or method.
This is the line and method and question:
calcArray.push( motif );
Any suggestion or way around to make this function to work in IE? Thanks for you help in advance.
javscript source is at:

Hi all, just in case someone is interested in my original post. it seems that IE does not support the push function?!! So i have changed the function that was giving me troubles;
calArray.push(motif);
by the following;
calArray[calArray.length]=motif;

and it works.
cheers
