Difference between values in a column

[#1]

Hello Community,

i have a quesetion.

I attached a QV-file that shows two columns, Data and Value.

I tried different tecniques to solve my problem but no one worked.

I want that the difference between ABC 1b and ABC 1f, ABC 2b - ABC 2f, ABC 3b - ABC 3f , ABC 4b - ABC 4f  should be calculated.Has anyone an idea?

best regards,

aylin
