>I have a textbox, Name: Text4, ControlSource: m.delegated and I want to only allow 'Y' or 'N', which will update the table of the logical field (org.delegated). What do I put in for the InputMask or Format for the textbox of the form? I tried TRANSFORM() but didn't work?

Chuck,

Use Y as the InputMask property. This will limit the input to Y and y and N and n, and properly make the conversion provided the ControlSource is a loggical field in a table.
