Conditional Formatting on Interactive PDF Drop-Down Text Field

I'm converted my interatcive PDG into a Form.

Using a "submit" button, I have added in the following actions upon a Mouse-Up click of the button.

1) Run JavaScript
2) Submit a form (mailto:) 

The following is what I have listed as the script but it doesn't seem to be working. What am I doing wrong? Any advice?

var f = this.getField("Budget Status");

if (event.value=="YELLOW") f.textColor = color.yellow;

else if (event.value=="GREEN") f.textColor = color.green;

else if (event.value=="RED") f.textColor = color.red;

else f.textColor = color.black;

var f = this.getField("Design Status");

if (event.value=="Either client is happy with the design & team is not, or team is happy with design & client is not.") f.textColor = color.yellow;

else if (event.value=="Client is happy with design & team is proud of the design.") f.textColor = color.green;

else if (event.value=="Neither team nor client are happy with design.") f.textColor = color.red;

else f.textColor = color.black;

var f = this.getField("Craft Status");

if (event.value=="Team is proud of the quality of the diagrams and/or drawings issued/to be issued.") f.textColor = color.green;

else if (event.value=="Team is not happy of the quality of the diagrams and/or drawings issued/to be issued.") f.textColor = color.red;

else if (event.value=="There is room for improvement on the quality of the diagrams and/or drawings issued/to be issued.") f.textColor = color.yellow;

else f.textColor = color.black;

var f = this.getField("Schedule Status");

if (event.value=="Project is tracking with distributed design & documentation schedule.") f.textColor = color.green;

else if (event.value=="A project design schedule has not been distributed.") f.textColor = color.red;

else if (event.value=="Project is slipping from distributed design & documentation schedule - update required.") f.textColor = color.yellow;

else f.textColor = color.black;
