Coding Button

["Lennox Jacob" <lenpartico at hotmail dot com>]

I have two EditFields named Ht and Wt, I also have a Pushbutton named 
BMIPushButton, which is  disabled and not defaulted at startup. I want the 
Pushbutton to be enabled and defaulted only when data is input into both Ht 
and Wt editFields, I did this
if (Ht.string and me.string) <> 0 then
   (BMIPushButton.enabled, BMIPushButton.default, BSAPushButton.enabled and 
BSAPushButton.default) = true
 else (BMIPushButton.enabled, BMIPushButton.default, BSAPushButton.enabled 
and BSAPushButton.default) = false
I also tried it with EditFieldHt instead of Ht.string.

Please help.
Thanks.
Lennox.
