You could do it as.........
Using text value based conditions in your report
Textbox1.enabled = (Condition_In_Report = "Text_Value")
Using Numeric based values in your report
Combo1.Enabled = (Condition_In_Report = 6 or 9 or (12 and 3))
Just replace the numeric or text values that decide wether the control should be enabled or disabled.
Textbox2.Enabled = (Budget < Maximumvalue or Today = "Monday")
You always mix and match too
