Isolating text string in a field

[McG]

I have a field currently set as a checkbox set (values such as maths, English, art, PE etc).

Assume the options maths and art are chosen.

I want to create a script that examines this field and if it finds a specific text string (maths), then a new record is created in the appropriate related table.

Right now my script will only work if a single option is chosen (maths only say), because I am simply using “if field = art”. I need “if field CONTAINS art”.

Any ideas?

Try:

not IsEmpty ( FilterValues ( "art" ; CheckboxField ) )
