Is there any difference between the echo syntax in your longer and the working shorter script? Basically you have problems with single and/or double quotation marks it seems. Maybe try playing around by escaping them with a backslash until you get the desired output.
Another way might be putting the statement to a plain file and then hand it over as a parameter to your script to have less hassle.
Also use CODE-tags when posting code, data or logs in future please.
