I would like to have several conversion scripts run on a single html page... 
Right now, one will work, but the others will not. Want to have them
all available and function.

Thanks in advance!
Example of 2 of the scripts:

I think this should be written by using setTimeout("method()",1000);

Hi dpakoh-ga!  Thank you for the quick reply....

That sounds ok, but I have no idea what that means or where to add it.
I understand the code, sort of, but have no idea what makes it work
(and not work).
Do you know how o make this work?

You can either:

Make sure the variable names are not duplicated thought all the codes 

or

you can just add html iframes each containing a script.



I would choose option two.

I'm too lazy to fix the scripts.
