Sorry for delayed responce, long weekend. 
Yes the useage with no code gives the same error so its definately the library declarations.
I installed the ServoTimer2 zip library and then
The switch to servotimer2 gets a scope declaration error.
So I tried to compile 'Threeservos' example, it also gives scope declaration errors
see 'servo2 libs text'
I'm not much of a C programmer so precisly where to create the missing variables eludes me.
I thought the example should work straight away?
When I get the example to work I can move back to my code.
