Dear Nand,
Please remember that assignment operator (=) is different from
"equal to" comparison (==). Also boolean conditions have to be
combined using AND/OR:
buy= condition1 == 1 AND condition2 == 1;
But all these stuff is pretty redundant because you can write:
buy = condition1 AND condition2;
Best regards,
Tomasz Janeczko
