perfect...thanks Roger...hope the backlash wasn't too bad

Hello all, my first post. I should have joined ages ago. I have run into a problem though. I have found a song added it to a songbook, changed a few chords and saved. I have changed the layout to uke (from guitar) and clicked on the change button. Now the problem I have is that when I open the song the newly changed chords are over the text, but the chord icons are for guitar, and when I use the drop down box to change to uke, the chord names over the text reverts to the original version (before I edited it)

I'm sure I must be doing something wrong, but I can't figure it out. Any help would be greatly appreciated.:)
