Returns half-width numbers. If you do not want full-width numbers to appear in a certain field information, you can use this function, for example:
[field:listnum/] returns 122３４ , I hope it is a half-width number 12234. You can use the function like this:
[field:listnum function=”GetAlabNum(@me)”/]
