In your Win95 working folder, pull down the View menu and select Options. Select the View tab. The load command in your script specifies the absolute pathname of the PDB file in RasMol, which never works in Chime. The PDB file needed by your script is missing from your working folder. Your PDB filename ends in .ent instead of .pdb .
Some websites end their atomic coordinate filenames with .ent instead of .pdb .
You may also wish to color key words in the text you add to right-a.htm so they match the relevant parts of the view. You may use several colors for different parts of one button-label. See, for example, the second button in right-a.htm . More than 256 color names are defined in Netscape. However, except for white and black, it is difficult to match the color names to the colors used by RasMol.
