bold inside IIF finction

pele

I try to add tag inside IIF finction

IIF(1=1, 'text1' + [b]'text2'[/b],'')

In designer, text2 is bold, but when I click Preview, I get an error: Error in expression IIF(1=1, 'text1' + 'text2',''): ')' expected.

I don't know why?

Use [IIF(1=1, 'text1' + '[b]text2[/b]','')]
