Should be an easy task...from another button I can say

thisform.shpbox.backcolor = '0,128,128'

But if I do when I run it I get the error "Datatype is invalid for this property"

if I try

thisform.shpbox.backcolor = 0,128,128

We'll obviously this won't work, I can't even get past closing the method window with a syntax error.

Is there another way? I can see the light at the end of the tunnel! Hopefully there's not another tunnel around the corner. Many thanks!
