When creating a new publication pattern, entering a four digit number into the “Number of issues published per cycle” field causes the page to hang because the “Days of publication, per cycle” section is being generated. Checking the number is within range beforehand will help prevent this.

The following validation should be applied:

• Cycle length = 1 day, Number of issues limited to 1

• Cycle length = 1 week, Number of issues limited to 7

• Cycle length = 1 month, Number of issues limited to 31

• Cycle length = 1 Year, , Number of issues limited to 365
