Hide columns if all cells are blank or £0.00

[Atticgirl]

I have a workbook where Sheet2 scrutinises data contained in Sheet1 (Sheet1 changes daily).
On Sheet2 I wish to keep rows in range H:Y visible if they contain a value greater than £0.00 but hide them if all cells in the column are either blank or £0.00.
Where cells contain a £ value this value is derived from a SUMIF formula that looks at Sheet1.
I need code for a macro button to hide columns if these conditions are met, and to unhide them again. I am very new to Excel, macros and vb so need code I can just copy and paste! Can anybody help, please?
