it would help if you put the contents of your script instead of the command dump. You are setting the style, seems to work fine, then you go through the style command again but not correctly, then partially again, trying to launch a find command (more on this in a sec) as the font file. Then try to change CONCRETE using FIND which you didn't launch above in a way that AFAIK you can't. FIND is not a command line usable command.
Again, type the commands in, one at a time, manually in a drawing. What you have to type to get it to work is EXACTLY what you need in the script. Why did you decide not to use chtext.lsp?
