invalid-value-for-Float():-"50---100".md

+I followed the guide on how to set up action text with administrate gem
+[https://github.com/thoughtbot/administrate/wiki/Field:-RichTextAreaField](https://github.com/thoughtbot/administrate/wiki/Field:-RichTextAreaField)
+
+[https://github.com/thoughtbot/administrate/wiki/Rails-6-&-Webpacker](https://github.com/thoughtbot/administrate/wiki/Rails-6-&-Webpacker)
+
+I successfully implemented all the code. 
+ 
+On the administrate admin, I get this error when I want to view any record with action text custom field
+`description: RichTextAreaField`
+
+`ActionView::Template::Error (invalid value for Float(): "50 - 100"):`
+    `16: [1]: http://www.rubydoc.info/gems/administrate/Administrate/Field/Number`
+    `17: %>`
+    `18: `
+    `19: <%= field.to_s %>`
