Dear ABB family,

A student here!
Can someone please help me with this syntax error. I send the photos for your better understanding. 

Thank you very much.

Where is the declaration for W_VarX, W_VarY and such?  It seems to be saying that they are not of the num type, but Signalgo type.

Thank you for your feedback. The problem was using; ":=" instead OF  SETGO
