Don't worry, I've got it sorted. There were smart objects that won't translate to FW. Once placed as normal layers it all works well.
Just a thought: However you converted the Photoshop PSDs to Fireworks PNGs, you could possibly follow a similar procedure to convert the Smart Objects to Fireworks PNGs and then to Symbols.
Thanks groove25. I'll give that a shot next time. I was prototyping and rather use FW for that but I needed the settings and as much as I could from the PS original. I haven't tried yet, but when I import a symbol it won't give me the values of let's sa a gradient.
