Is the type of your column you want to use ok (depending on the type of symbology you want to use)
?
If you want to use a graduated symbol, you need to have numbers. If you data has string as type, you can easily use an expression (the little button next to the drop down) to 'cast' your string to int or double. Another option is to fix this in the join or your original data.
