Solved Validation rule at least 6 characters

[Kayleigh]

Please can someone help with the syntax to write a validation rule for a text field to allow no less than 6 characters of alphanumeric characters.

Thanks

Len([YourTextColumn]) >= 6

that doesn't check for non alphanumeric characters - suggest

Len([YourTextColumn]) >= 6 and not [YourTextColumn] Like "*[!0-9a-zA-Z]*"

I would also Trim([YourTextColumn]) either before CJ_London's code is run. Anything like this I use Trim() as a matter of course.
