Drop shadow glow colored with white font over transparent background. Color won't show without a colored background

Drop shadow problem--I used the DS to create a glow effect. On white text, set to add and colored blue. I used a page background of black-k100. It shows up the color fine over a background. But I need a transparent background. In the white space outside of the page, or after exporting as png, it doesn't show color. The glow effect is white unless over a background. The text is three layers of text with different size and hues of glow.
How do I get the colored glow with transparent background?
I've tried several different save methods. I thought the page background color was just to work with and when I saved our exported that it would not show up.
I just needed a color workspace to see white text. I'm frustrated with this. Any help?
