IF(X>99%, copy and paste cell Y into cell Z, do nothing)

Hi,

I'm very new to learning VBA and I'm looking for a macro that can do the following: -

- Look at every cell in column C (C1:C100), and if the value in that cell is over 99%, copy and paste cell E1 (a fixed value) into the relevant cell in column A (A1:100). If the value in column C is under 99%, leave relevant cell in column A as it was.

I hope this makes sense, if any further clarification is needed, thats not a problem.

Thanks in advance for any help.

Dan
