If you have time can you please assist me with the following - something I have been battling with for weeks and I only realized now that I could get help via this forum - Rolling PCA and extracting variance explained by 1st PC (time series)
I have attached the workfile,program and a excel spread.

The workfile has the data (time series) of following - ZAR , VIX and EM
Program code is rolling PCA - please can you see what I am doing wrong.
