Hi,

==> “The return type of the expression must be Boolean”

You have defined a variable as boolean and the return must be the same type. If you want I can check your process if you have TV.

I resolved the problem by creating my own org not using default test organization.

Hi sylvain,

Thanks for your reply. I don’t know if you meant “TV” by team viewer. Sorry I can’t enter the code for connecting here. Do you have skype or other contact method? Thanks.

I can be contacted via james.newaim@gmail.com
