Hello,
When I use +ConstantName pips i get compilation errors.
Compilation errors
'pips' - undeclared identifier
'pips' - some operator expected
Screenshot (banda_arriba is the constant):

When I use +VariableName pips i get compilation errors, as well:
Compilation errors
'ancho' - undeclared identifier
'pips' - undeclared identifier
'pips' - some operator expected
Screenshot (ancho is the variable):

I don't know what I'm doing wrong...
Thank you in advance for your help.
David
