    Radio Buttons and colour selection


      I'm having trouble with a fairly basic function. I'm trying to change the colour of a line that will act as a scale bar over an image from a microscope. Students have to choose between a white bar or a black bar depending on the selection of a radio button. I've written the code to listen for the selection and put the function for choosing the colour inside the function that draws the line, but it keeps selecting the first colour in the "if" statement, that is It's tracing "the line is black" even before clicking a radio button. It will trace a change in the selectedData colour but doesn't change the colour of the line.

      I'm sure it's something really obvious; I'd really appreciate a fresh look at this.

      Thank you very much,
