Problems finding the next empty cell and paste value

Hi everyone,

I tried a lot to find out how to find the first emtpy cell and paste values in this cell. But I had no chance. There are a lot of examples in this forum, but I couldnīt find the right one. So please help me.
I have the following problem:

Sheet "input": the values are always at B5 (as text), C5 (as EURO), E5 (as text) and F5 (as EURO)
Sheet output: -Search for the first empty cell AFTER B3 and copy the value from sheet "input" B5 to this cell and the value of sheet "input" C5 right to the this cell
Then search for the next emtpy cell AFTER B3 an copy the values form sheets "input" E5 and F5 in the same way.

Thanks a lot
Kind Regards
Roman
