Voucher Codes "TYPO Invalid magic"

[MohamedMagdi]

Hello Guys, I'm facing a problem with voucher codes i just want to make them only numbers and if i change Character set to numbers only i get that error "TYPO Invalid magic" if i back it to letters & numbers it works fine without problems, so how can i make it only numbers without errors

–----------------------
Thanks Guys

if you want only numbers, then you should probably set it to: 1234567890

Add to that:
What are you trying achieve with a "Character set" like "1020304050607080" ?

if we change these character to number would it effect the existing voucher??

Make a backup …. and try it out - I'm NOT gonna do that for you ;)
