Should I create a filter by post code, but sometimes from beginning is letters, but sometimes not.
How to use in filter only numbers?
I need to find out Customers by post code (for example) NO-2100 and 5010.
For me usable is only numbers like 2100 and 5010 - how to "delete" this "NO-"?
p.s. Sometimes post code will be longer as 4 numbers...
