i have a made a custom control. which has text box and drop down . text  
box has the value and drop down has a units if you change the units the  
value will change accordingly . the problem i am facing is, when i  
change the units the value changes but when i inspect the field in  
firebug the value of the text box is still the old value. hope i am  
clear and thanks for the suggestions.

Firebug lies sometimes and that might be the issue. Did you try to  
check the value using JS console ?

ok i tried this when i alert($(‘unit\_text\_box’).value) it shows the new  
value . but right in the next line when i say $(‘unit\_text\_box’).value  
and try to use it in a if condition, it evaluates to the old value  
rather than new value as shown in the alert.
