Is there a way to add a variable between two other variables? So we have officehide and cellhide, but if both numbers are there we want a | to separate. Would it have to be one giant formula or multiples?


1. From Signature Designer go to Admin > Fields

2. Create a new Field

Type: Select Formula

3. Copy and Paste the below code snippet (also attached): into the Formula Editor:

string strPhone = "(!Phone!)";
string strMobile = "(!Mobile!)";
string strFax = "(!Fax!)";
List strMulti = new List();

if (strPhone != "")
strMulti.Add("Tel: " + strPhone);
if (strFax != "")
strMulti.Add("Fax: " + strFax);
if (strMobile != "")
{ strMulti.Add("Mobile: " + strMobile);

return String.Join("| ", strMulti.ToArray());

NOTE: The separator, below can be changed to another value eg ","
