do you think you can help me?

In sheet2 I have in columns C and D some numbers. but numbers arent in all cells, eg C1 is numbered,C2 empty,C3-C6 numbered,C7 empty,C8 numbered etc. The same for column D.

I need to make some macro which will copy only cells with numbers from column C to sheet1 (=will copy cells C1,C3-C6,C8 from sheet2), but...in sheet1 i have table 40x4 cells (C1:F40). Imagine that macro will find cca 100 numbered cells from columnd C in sheet2 - i need to put these numbers to table C1:F40 in sheet1 ->first 40 numbers will be in C1:C40, the 41st will be in D1 and so on,81 st in E1. It is easy to make it handy, but I'd like to make some macro.

The same way for column D in sheet2 -> copy only numbered cells from Sheet2 to Sheet1,column A

Would be great if you can help me.
