List box expression bit tricky

[#1]

i have a list box in the below qvw

in my scenario i have to Exclude or restrict the field values which are having starting letters 's','r','m','j' in salesman field whether it is upper or lower we should exclude those salesman names.

You can use this expression instead of a field: =if(not WildMatch(Salesman, 's*', 'm*', 'r*'),Salesman)

thanks for your support Wassenaar.
