to create list box with expression

[cristianj23a]

Hi.

I need your help.

I want to create a list box that filters an expression.

for example.

create a list box that shows me a range of values in the expression.

but when it filters the value from 0 to 1000, it does not fulfill the request.

The values should be greater than zero and less than one thousand

Help me with this subject please.
