I HAVE A SCREEN WITH A POLYGON. I CAN CHANGE THE FILL COLOUR USING A PRE COLOURED BUTTON.
I NEED A BUTTON WITH A SCRIPT THAT WILL ALLOW ME TO CHANGE THE POLYGON COLOUR TO A SPECIFIC RGB COLOUR.
ANY HELP IS WELCOME.
USING V7 AND V7 OF OPUS PRO

Capitals is shouting.

If you're using the change polygon fill action, click the help button on the dialogue - it explains how to use the variable. Best option is three input boxes, then script on button that uses RGB function to covert the above three input box variables to the RGB value and assign this to the variable used in the action.

Thanks for your help,
i understood the concept but failed miserably to get my polygon to change to the required colour (kept getting errors)
i managed to create 3 text input boxes, one for red called RED, one for green called GREEN, one for blue called BLUE.
i can enter the desired value in each box, i have created a button called RGB
i choose variable for change polygon fill, variable named RGB_INPUT
i added a script to give to RGB_INPUT the values for my RED, GREEN and BLUE boxes but have been getting repeatedly some syntax errors.
i attach my .imp file created in opus 7.
i use to background to test dyslexic children vision, they respond sometimes to a very narrow colour range and can read better under those conditions.
later i will have to design the background colour to change according to HSL values either by data entry or better by using 3 bars that will allow me to change one value at a time. this is to mimic an instrument costing few thousands dollars.

You have to RGB the values before assigning to the variable.
