Text cannot be transparent - but it can be the same color as the background.
the problem is that i'm in a portal with alternating background colors and I'm merging information in the portal so when one type of info is irrelevant it minimizes based on a formula and the other info shows up in it's place. except for some dots and spots i'm almost there...
It's possible to match the alternating color, but it's rather complicated - why don't you simply use a calculation field in the child table to select the appropriate value?
I appreciate your comments. I went back and created my own background colors for the various types of portal rows and that allowed me to phase out inappropriate text, and it looks better than alternating colors. Thanks for your help!
