when rowcount = 3, I need to select cells A3 thru H3

when rowcount = 5, I need to select cells A5 thru H5

I have tried a few things, but I'm missing something

' rowcount count's thru the rows of a sheet I have

I have;

a_num = rowcount
h_num = rowcount

cells("a_num:h_num").select

This doesnt seem to work

Can anyone suggest somthing I could try?

Thanks
