Oops! I forgot the HTML parser would remove all the extra spaces in my example. So here it is again. Think spaces when you see periods.

For example:
Text1.Value = 'David.......'
Text2.Value = 'Fluker......'
Text1.Value + Text2.Value = 'David......Fluker......'
If I put this in Text2.Value, it looks like Text1 has written over Text2 because I cannot see the "Fluker". I can click on Text2 and scroll right to see the rest of the value.

To fix this you need to trim the extra spaces with something like
Text2 = ALLTRIM(Text1) + ALLTRIM(Text2)
or
Text2 = Text1 - Text2

David.
