</div>

I would print the following to the console to make sure the component really exists:`print 'NEW_MOTOR_RPM_STD%d' %cn`My guess is the name is incorrect.

yes the name is absolutelty perfect

actually we upgraded recently to v7.3.1 32 bit  
and since then we are facing these issues

even the pages with good designs and colors are now turning to gray scale,  
during runtime and the actual configuration done is also affected.  
even the fonts and font size and colors are being changed automatically ( to Dailog, plan, 12)  
please check teh below images for your reference

Robin - as another approach, it may be easier to bind the background property to an expression that sets the color based on that pfin value instead of using scripting.

I am new to the board, but in a spirit of ‘better late than never’, here is the solution to the issue. The syntax was wrong as there is no ‘rootContainer’ method, there is getRootContainer().

Wrong Syntax-  
system.gui.getWindow(“LS\_CALC”).rootContainer.getComponent(‘NEW\_MOTOR\_RPM\_STD%d’ %cn).background = (223,222,222,222)

Correct-  
system.gui.getWindow(“LS\_CALC”).getRootContainer().getComponent(‘NEW\_MOTOR\_RPM\_STD%d’ %cn).background = (223,222,222,222)
