How did you format the field as "Bold" on the first layout?
Did you select the text in the field and select bold while in browse mode or did you select the field while in layout mode and specify a "Bold" text format?
If you did the second option, this style will not appear when you add the field to your second layout and it should then appear as plain text unless you select the field and specify a different format.
But any sytles applied directly to the data in the field will override the styles specified for the field while in layout mode...
This was the calculation for Table 1 Title:
Let ( [text = TextStyleAdd ( Self ; Uppercase+Bold) ; w1 = LeftWords ( text ; 1 )] ; Case ( not IsEmpty ( FilterValues ( w1 ; "the¶an¶a" ) ) ; RightWords ( text ; WordCount ( text ) -1 ) & ", " & w1 ; text))
In that case, you'll need to add a new calculation field defined as:
and you can put that on your layout.
Or you can remove the TextStyleAdd function from the above calculation and just select the field on your original layout and specify a bold text style.
That will display the title in bold only on that layout so that other layouts can specify different styles as needed.
