chart titles

[Bob]

I have a report that displays a chart of acidity over
time. The chart is based on a parameter query that
selects acidity data for a particular formula.

I want to display above the chart (in the header section)
other info (like the formula #) that's included in the
query. I tried inserting a text box, but everything I
enter in the 'data, control source' results in "name?"
when I view the report.

Any ideas???

Thanks, Bob
