==================
Good day. I'm looking to force a minimum of 3x characters for the "Other" option in a List (radio) question. I searched for a while now and found the following on the forum:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#question{QID} input[type="text"]').attr('maxlength', '3');
});
</script>

I tried changing maxlength to minlength but this didn't seem to work.

Another option I saw was to use regex but not sure where one would include this (and if the regex is ever correct) ==> /^{3,}$/

Any assistance will be greatly appreciated.

Use question validation equation!
is_empty(Q1_other) or strlen(Q1_other)>2
