Hide Columns If Cell In Specific Row Is Blank

I have a row in a table from columns C to CZ. All the cells in the row contain a formula, between 1 and 204 cells in the row will have a value (i.e. will not be blank).

The cells with a value will start at column C and may or may not have a blank cell before no more values and blank cells to the end (Col GZ).

Example:

C D E F G H I J K >..........................GZ

23 34 67 74 2 34 6 2 56 all blank ("") to end

or:

C D E F G H I J K >..........................GZ

23 34 67 "" "" 34 6 all blank ("") to end

I need to hide the entire columns when the cells in this row are blank but NOT if the blank cell has valued cells after it (i.e. do not hide columns F and G in the second example.

I can do this by looping back from col GZ and hiding the columns one at a time, which is very slow. I am stuck on the code to select all the relavent columns and hide together.
