Hi,  
I have Float4 memory tag and Numeric Text Field with bidirectional binding.  
If I enter 2,55(with comma) to Numeric Text Field, everything is ok. But if I enter 2.55 (with period) by mistake, I will get value 255.  
I tried to replace “period” to “comma” such script:  
if event.keyCode == event.VK\_PERIOD:  
event.keyCode = event.VK\_COMMA

But with no luck.  
How can I replace “period” to “comma” during enter?

You can use the Java Robot to erase the period and enter a comma:

[code]from java.awt import Robot  
from java.awt.event import KeyEvent

if event.keyCode == event.VK\_PERIOD:  
rob = Robot()  
rob.keyPress(KeyEvent.VK\_BACK\_SPACE)  
rob.keyPress(KeyEvent.VK\_COMMA)[/code]
