Select in Field multiple selections with parentheses
I need a button to select multiple values, which I understand the syntax is (value1|value2). However, my values have parentheses in them. For example:
a) $1 - $2
b) $2 - $5
c) $5 - $10
If I try to place it in the syntax to select multiple values, the parenthesis in each value closes the syntax that accepts multiple values. I can't use single quotes or double quotes to contain the string. I've tried setting variables to the strings I want to use and placing the variable name into the syntax like ($(vOptionA)|$(vOptionB)) but this does not work either. I cannot modify the data.
Can anyone help me how to select in field for multiple selections if those selections have a closed parenthesis in each of them?
