Hi Bruce,

Maybe try setting the input mask based on the contents of the field. Kind of a dynamic input mask. You could use the textbox InteractiveChange() event to set and clear the mask. For example:

Try this code in your TEXTBOX InteractiveChange() event:

LOCAL nPosition
IF EMPTY(THIS.Value)
THIS.Format = ""
THIS.InputMask = ""
THIS.Value = ""
ELSE
IF EMPTY(THIS.Format)
m.nPosition = THIS.SelStart
THIS.Format = "R"
THIS.InputMask = "(999) 999-9999"
THIS.SelStart = m.nPosition + 1
ENDIF
ENDIF

"M" is used in the Format property to specify multiple values that the control can be set to, not to specify multiple input masks. Try the following to demonstrate how this works:

1) Create a textbox on a form.
2) Set the following properties:
Format = M
InputMask = Apple,Orange,Banana
3) Run the form.
4) Press the spacebar in the textbox.
