main report has subreports that are truncated

[Pat]

I have a main report A with 3 sub reports (B, C and D) followed by a further sub report E that has 3 sub reports (F, G and H):
My problem is that sub report D which sits to the right of C is truncated.
I have made A and E to be Landscape with all other Portrait.
A is 24.5cm wide with short margins.
E is 23.5cm wide with short margins.

Any ideas as to why C is being truncated?

All good, i had one of the subforms that was not defined wide enough. Silly me.
