Need to Subtract Measure for Current Time Period from Measure for Previous

I am not sure if this is a Set Analysis Question or not.

Basically I need to subtract the current time period measure from the measure for every time period across the dimension.

I do not have the "Variance from Current Quarter" in my dataset. I need to calculate that.

I took my crosstab table and made it longer by adding the Measurement Column, to take place of the data I recieved, which came to me like this:

I did it through some scripting. I don't think it was the perfect answer, but it works.
