Copy data from one sheet to another in the first empty column in a given range

Dear All,

I would highly appreciate your support on a very simple macro, since my knowledge in VBA language is very poor.
I would like to be able to copy a range of data from the Master sheet into another sheet (Sheet1). The data needs to be copied into the first empty column found, but in a given range.
For instance, to copy from Master column B and C and paste them into Sheet1 in the first empty column found in range G to M (column A to G and N to Z always have data....only the range G -M might have empty columns and there I want to copy the data).
Next time I run the macro, again, to find the next empty column and so on.

I highly appreciate your kind help.

Thank you very much and looking forward for your replies.
