Can I limit a list box contents based on the frequency

[gfisch13]

Hi All - I have a list box that contains bank accounts with the frequency of each account listed.   I would like to limit the values in that list box using the frequency.  I'm not sure how/where to write that expression.   The frequency is obtained by clicking the check box for 'Show Frequency' on the list box general tab.   Any help is appreciated.

Thanks, George

Hi George,

Frequency is just count(). It can be done.

Example, i filtered to show bankaccount no count is more than 1 in the below example. find the attachment.
