Find Non Blank Cell and run Macro

[Vetequk]

I am try to write a bit of code which will find the non blank cells in column H (Range H4:H24) and when it finds a non blank cell make column C in that row the active cell and then run a macro. Once the macro as been run i would like it to look for the next non blank cell.

At this moment I do not have any idea where to start with this so any help would be appreciated.

Thanks Vetequk
