Hi PaulS.
The solution maybe stupid to you, are you implying i am stupid, if you are you are the first man in my life to do so, and from someone who does not know me , i find very offensive. I have a First Class Honors Degree in Mechanical Engineering, From Leeds University, UK. Stupid!
I thought i had removed all of the quotation marks, i attach a screen shot of my problem, the sketch stops on the red line, i see no quotation marks, only brackets.
