    Well, you set that variable a few lines earlier via:

    PHP Code:
    $product_name1=substr(trim($arrayProd[$m]),0,strpos($arrayProd[$m],"(")-1); 
    You need to debug all the variables involved (echo their values) and see what's going on.

    If the results are what you expect, then do the same thing for this line:

    PHP Code:
    if(strcmp($row2['fullname'],$product_name1) == 0
    See how the variables are set, and confirm your logic for that "if" condition.

    Respectfully, your question was asked and answered, there is no need to repeat yourself.
