I need to set up a vb script such that if a user types a number in the field, it is replaced with a symbol.

Question:
I have a client who needs to automatically convert any number typed (in a certain field) into an associated glyph.
For example:
1 = •
2 = è
3 = Ò
etc.
 
Answer:
You would use the the replace function.  You would need to nest them together.  Your script would look like this:
 
replace(
replace(
replace(
FieldName, 
"1", "•"), 
"2", "è"), 
"3","Ò")
 
The linebreaks have been added for clarity.  You should remove them when using in eDoc.  You would replace FieldName with the actual field name.
