Thanks for your reply.
Maybe I wasn’t very clear, sorry: There’s no animation or counting. The number just needs to be displayed with a K, M or B depending on if it’s in the thousands, millions or billions. This is for a MOGRT to be used in Premiere by people with no AE experience, so if they were to type 4,6000,000,000 then the expression would automatically convert it to display as “4.6B”.
After sleeping on it, I think I’ve just got carried away with my new expressions knowledge and tried to be too clever. ????I think I’ll replace it with a simple text box for the number (or a 1 – 999 slider) and a series of checkboxes or a slider for the K/M/B suffix.
