I am building this with Apex 3.2
I have a validation on a page item of type regular expression
Validation Expression 1 : P13_TARGET_BMI
Validation Expression 2: ^[[:alnum:]-]*$
This allows all characters, number and the - symbol
Now I need to exclude certain alpha characters, ie German letters Ä Ü Ö
and spaces if possible
Basically if the user types in Ä, Ü, Ö, the validation should fail
Cheers
