Error when addin fields in a form

Code Examples Form
#1

Hello,

{field4} = {field1}+{field2}+{field3};

I have this line of code on ajax event (field3 on_blur), and i get this error
Parse error: syntax error, unexpected ‘$this’ (T_VARIABLE), expecting ‘(’ in C:…path\form_trsf_reservation_apl.php on line 6812

It happens now that i have updated to sc 7.1, before worked fine.

Anyone knows why?

Tanks in advance

Grab that file form_trsf_reservation_apl.php and check line 6812, it should give you more details.
