Yes, My fault. Accoring the documentation (Developer.hlp), you can use:
oReport.formulafields("WhatEverName").Text= cYourFormula.

B.t.w., Do you need to change the formula, or do you simply want to pass a variable to the report. Then it might be better to use parameterfields. for example:

WITH oReport.ParameterFields
	FOR nT= 1 TO .Count
		cName=.Item(nT).ParameterFieldName
		IF TYPE(cName) # "U"
			.item(nT).SetCurrentValue(EVAL(cName))
		ENDIF
	ENDFOR
ENDWITH

In this way you pass variables defined in VFP to CR, if the variables in CR have the same name.
