Thanks Kevin for the tip!
A similar problem are url parameters like [brand] [model] [browser] [city] etc. - we need to delete the echoed parameters (displayed at the time the lander was ripped), and leave only the tokens.
EDIT: Oops! I meant replace with the tokens plus the corresponding js code required to display those values.

Hey Kevin,
haha finally someone came out with this one! Its easy mistake even for seasoned affiliates as for example if you spy manually and save the lander then you will have the current date on it, so it seems to blend in and it's easy to forget.
In general - this happens with all JS printed code, so yeah watch for it!
Yep haha have been guilty of it as well in the past 
And seeing this way too much lately.
Another one:
If someone uses PHP to print the custom paramters like {brand} and {model} it'll look like "static text" at first sight , something like "We selected this for loyal customers from London with Samsung phones" , no JS code to spot something was generated individualy here , since the spy tools can't rip the PHP code.
In this case you always have to replace the printed out individual parameter with your own JS code - it can take quite a bit of time if you're being careful and detailed.
