I have a 2x2 matrix question - 1 row for Highest and 1 row for Lowest. How do I validate that the value entered into the Highest field is greater than the value entered in the Lowest field?

How do I validate that one field in a matrix table is a greater value than another?

Edit: Solved using custom validation with regex matching to ensure only numbers entered and then Piped Text for the comparison of values.

+1qualtrics_user_007 here is a snippet of the custom validation: 
the regex I used for digits (since it's slightly cut off in the screenshot) was: /\\d+(,\\d{3})?(.\\d{2})?/ - this allows numbers like 1, 100, 99.00, 10,000 and so on.
basically the first two regex conditions ensure only numbers are entered and then the third line compares the two inputs and ensures the value in the Highest field is greater than that in the lowest field. I pulled the input in the Highest field as Piped Text for comparison.
hope this helps.
