Hi

How is your column data joined ? with a "space" or with a "coma"?

You can use the split() function:

split(<your field data>,<your separator>).GetValue(<index>).ToString

For example if the field contains "Big,Small"

To get the first value "Big"

You can do a split("Big,Small",",").getValue(0).ToString --Not sure if the index begins with 0 or 1 / have to test it
