I was able to get this sorted.  Had to dot walk into the name field, also changed up the code a bit.  Working now.

var un = current.variable_pool.requested_for.user_name;
workflow.scratchpad.username = un;

var reg = current.variables.requested_for.location.u_region.name;
var loc = current.variables.requested_for.location.name;

if (reg == '721') {
workflow.scratchpad.group = "Inventory Search Midwest - BO";
}
if (reg == '725') {
workflow.scratchpad.group = "Inventory Search West - BO";
}
if (reg == '810') {
workflow.scratchpad.group = "Inventory Search TCI - BO";
}
if (reg == '723') {
workflow.scratchpad.group = "Inventory Search Southwest - BO";
}
if (reg == '724') {
workflow.scratchpad.group = "Inventory Search Southeast - BO";
}
if (reg == '722') {
workflow.scratchpad.group = "Inventory Search Northeast - BO";
}

if (loc == '880') {
workflow.scratchpad.group = "Inventory Search Catalog - BO";
}
