'&' is a special character in the coding which needs to be 'escaped' or otherwise excluded. One approach is to use ATT instead of AT&T when this happens:
"mailto:"&""&[Email 1]&
"\n"&"?subject="&"\n"&[Record]&""&
"&body="&"Location Name: "& (If([Location Name]="AT&T","ATT",[Location Name]))
"%0D"
&"field2"&
"%0D"
&"field3"&
""
This might work also and retain the '&' correctly in AT&T:
"mailto:"&""&[Email 1]&
"\n"&"?subject="&"\n"&[Record]&""&
"&body="&"Location Name: "& (If([Location Name]="AT&T","AT&T",[Location Name]))
"%0D"
&"field2"&
"%0D"
&"field3"&
""
