After this statement all comments where echoed to the screen and echo didnt work.
For example echo $func would not show the content of func
Once I commented the line out - problem gone - so I presume there is something in the syntax of that one particular line that caused the problem.

There's a space after the second backslash, so that the quote is not escaped. It should (presumably) be:

Code:
echo "\"$location $plant $desig $quantity\" $rid"
