 hi all,

is it possible , to set custom field must to start 8 and 9

the case is the field will gather contact number

thanks in advance

Do you mean that any contact number that is entered will be either 9XXXX... or 8XXXX...?

Do you want an error message to be shown if someone enters say 7654... in the custom field?

I believe that this sort of customization usually requires some programming.

The general formula is (1) figure out which screens need the custom behavior, (2) write some Javascript to implement the behavior, and (3) inject the Javascript code on each screen. There's some examples on this topic:
