Excellent Suggestion! Here's what I ended up doing:
<cfset custCount ="#getCustinfo.recordcount#" + 1 />
format4.topborder="thin";
format4.topbordercolor="grey_40_percent";
format4.bottomborder="thin";
format4.bottombordercolor="grey_40_percent";
format4.leftborder="thin";
format4.leftbordercolor="grey_40_percent";
format4.rightborder="thin";
format4.rightbordercolor="grey_40_percent";
SpreadsheetFormatCellRange(report,format4, 2,1,"#custCount#",8);
Thanks a bunch!
