non-numeric value encountered

[JOSSm]

Hello I have changed my PHP version to 7.2
and i get this error 

(1/1) ContextErrorException

Warning: A non-numeric value encountered

in ratingsnippets.php line 720

This is the line:

 $rating_width = @number_format($current_rating / $count, 2) * $rating_unitwidth;

The error is in $ count because if I change it manually it works

Thanks in advance

Which version of PrestaShop you are using. Is this any native module or thirdparty module. The things is that @count variable has no value, please print {$count|print_r} or {$count|var_dump}  before it to check it has any value or not

 

Thank you

You can use PrestaShop native ratting module   it is addedd in core https://www.prestashop.com/en/blog/customer-reviews-module

or you can null exception the value via php so when value is null it will not calculate 

Thank you

The problem is that I already had a lot of punctuations with that module.
Is there a way to migrate the data from one module to the other?
Thanks for the help
