Here's a native QuickBase version that counts the characters - but note that it will not update until you leave the focus from the multi-line text field.
Fields:
- [Text] - multi-line text field, with "Max Characters" = 500
- [Characters Remaining] - Formula Numeric field, with the following formula
500 - Length([Text])
(you can change 500 to whatever your maximum length should be - matching the setting in the field properties of [Text])
[Characters Remaining] will start with "500". Once you type something in [Text], and you leave the focus of that field (e.g. by tabbing to the next field, clicking somewhere else, etc.) - then [Characters Remaining] will update to show the number of characters remaining after subtracting from the maximum character limit.
