Dropdown box selection to change background color of text field

Question

Hello, I wonder if anyone could please point me in the right direction of how to achieve the following:

Acrobat DC

I have a drop-down box which contains five items. I have managed to change the colour of the text for each item when selected within the drop-down box. What I would really like to do is to change the background colour of 5 different text fields as well. So selecting item 1 turns the text red in the drop-down and also makes the background colour of a text field red. selecting item 2 makes the text turn blue in the drop-down and also makes the background of an additional text field blue. And so forth... No selection means the colour is transparent.

I cannot get my head around this. If anyone could please point me in the right direction I would be eternally grateful.

Ok, I worked it out!I have the code in the 'Custom calculation script' for the text box. "input_project_1_early" is the drop down.event.value=this.getField("input_project_1_early").value; if (event.value=="MS") event.target.fillColor = color.blue;else if (event.value=="PA") event.target.fillColor = color.magenta;else if (event.value=="GP") event.target.fillColor = color.green;else if (event.value=="AP") event.target.fillColor = color.red;else if (event.value=="i") event.target.fillColor = color.black;else event.target.fillColor = color.transparent; event.target.fontColor = color.transparent;works like a charm.Thanks everyone for their replies.

Is anyone able to tell me why this doesn't work? From all the searching I have done I cannot see how else this is possible?

var newFillColor;

var value;

if (value=="1") newFillColor = color.blue;

else if (value=="2") newFillColor = color.magenta;

else if (value=="3") newFillColor = color.green;

else if (value=="4") newFillColor = color.red;

else if (value=="5") newFillColor = color.yellow;

else newFillColor = color.transparent;

event.target.fillColor = newFillColor;

this.getfield("input_project_1_early").value=value
