Step 1
First, visit your Currency Converter setup page and double check settings and setup there.
You will need to insert the Monto global script from that page into your Webflow Site settings > Custom Code > Head code section (you only need to do this once per app)
Note: this script is auto-inserted in BigCommerce or Duda sites
This is usually all you need to get Currency Converter up and running on an Ecommerce site!
Check what your site looks like using a VPN (Free app here).
If you're still seeing an error, then the most common thing is a formatting issue in your prices.
Step 2 (Ecommerce Site)
Check your currency format settings in the Webflow designer Settings > Ecommerce > General tab (or if using another website builder).
It should look like this:
[Currency Symbol] [Amount] [Currency Code]
The currency code is required as many currencies use the same currency symbol.
Be sure your "Amount Format" uses either:
Comma thousand separator (see above)
No thousand separator
The following formats will NOT work:
Space thousand separator
Period thousand separator
Step 2 (CMS Site)
Follow the instructions here for prepping your CMS prices: https://help.monto.io/en/articles/6395651-using-multi-currency-outside-of-webflow-ecommerce
Be sure to wrap the price in a span tag with the custom attribute mentioned in the article.
Format the price using no thousand separators and with a space between the symbol, price, and currency code.
GOOD EXAMPLE:
$ 1200.00 USD OR € 1200,00 EUR
WHAT NOT TO DO:
$1,200.00 OR €1.200,00
