custom attribute - limit digit within <> value - HowTo?

[panini]

Hi,

I've created a little mess, and am step by step trying to learn how to improve and how to correct.
Suppose I create a custom attribute, called year. It consists of 4 digits ####.
How can I e.g. limit the 3rd digit to be between >6 - 9< ?
So in the example only 7 and 8 would pass.

Thanks for your help!

You can try creating another condition where the custom attribute is on the left hand side. You can try something like "•Mycustomdate is after specific date <Dec 31 1959>" and "•Mycustomdate is before specific date <Jan 1 2000>" to try and limit it to dates within those decades.
