Hi I have several fields and I would like to know if there is someway to  
get the values of already typed text\_fields and get it’s sum, doing an  
observer field for each text\_field is gonna be kinda complicated.  
If there is some way to use javascript for each time I type tab  
uploading the value would be also desired  
thanks  
ps: the subject is only a way to get attetion =x

Please please don’t do this. It’s also a quick way to get people to  
ignore you.
