# Invalid ViewContent value parameter

 * Hi,
 * While using this plugin to connect to Facebook, we are seeing this issue on Facebook,
   regarding the pixel events:
 * > Issue: Invalid ViewContent value parameter
   >  One or more of your ViewContent
   > events has invalid characters in the value field. This may affect your ability
   > to see return on ad spend calculations.
   > Solution: Check source code
   >  Open your website’s source code. Locate the ViewContent
   > event(s) and update the event code snippet. The value field must contain a 
   > decimal number greater than zero, and may not include letters, special characters,
   > currency symbols or commas.
 * The products in question are products that are not currently available, so do
   not have a price. The pixel code generated by this plugin has this as the value:
 *     ```
       fbq('track', 'ViewContent', {
           "source": "woocommerce",
           "version": "4.2.2",
           "pluginVersion": "1.11.4",
           "content_name": "ATP Noway Collagen Bar",
           "content_ids": "[\"wc_post_id_158285\"]",
           "content_type": "product",
           "value": "",
           "currency": "USD"
       });
       ```
   
 * Judging by the error message, this either needs to be `0.00`, or omitted entirely.
 * Any help would be much appreciated.

 * Hey @jakept,
 * Thanks for writing to us about our plugin! I’m sorry to hear that the plugin 
   isn’t working as expected. I am happy to help out here. 🙂
 * I’ve done some testing on my own local development site and I can replicate the
   issue you’re having. Thank you so much for providing such a detailed report on
   this issue!
 * I’ve added this to our issue tracker for the developers to get this patched up.
   While I don’t have an estimated time for resolution right now, please know that
   our team is now aware of the issue and will work to incorporate a fix into the
   plugin as soon as they can.
 * In the meantime, though not ideal, I would recommend setting a price for the 
   affected products and ensuring that the products are set to “Out of stock” and
   aren’t set to sync to Facebook. This will ensure that customers aren’t able to
   purchase the unavailable products.
 * Would you please let me know if this workaround would work for your needs and
   if there’s anything else I can help you with?
 * Thanks,
    Tamara 🙂 SkyVerge
