Compulsary check: Wanting to set compulsory checks in certain fields I used the -required option of the InputFields command.  Is my understanding correct: that the -required option alone does not automatically carry out the compulsory check?
You are right, the "-required" option results in a visual indication that the field is required, but does not check that the user has actually entered a value. You need to carry this out on your own in the InputScript. Use  "Message" and optionally "SetCursor" to set the cursor into the missing field.
