I'm receiving an error message prompting me to enter a valid number.



If you receive an error message about "valid numbers" when trying to post your ad, itʼs possible that you weren't entering a whole number.

For example, instead of "120,000km" please input "120000". Please make sure you exclude any commas, periods, symbols, and letters — only numbers should be used. If you've tried this and youʼre still experiencing issues with posting, please contact us here.
