I am trying to solve a problem with orphaned group headers. The report comprise a group heading and 3 details sections. The problem I have is that I am trying to prevent header appearing at the end of pages without at least the first details record or if there is insufficient space the report throw a page break before the header. 

Thanks for the response I will have another go at the measuring. What I came up with before was to identify the fix size fields and with the variable field I took the field length divided by a number of characters and rounded put. I then added the length to a shared variable and then tied a calculation. Unfortunately I didn't seem to get it right. The difficultly was that the header used a different size font so it was difficult to estimate the number of lines. More experimentation required!

I think I have fixed it! Thanks to the suggestion I looked up the field sizes for the fixed data and used a formula to estimate the number of lines in the variable fields then multipled by an average line height. Once I had the sizes it was quite easy to create a New Page before formula, although only time will tell!!

Thanks for the assistance
