[AccessD] More data source issues

Thanks to Karen, I got the first problem handled.
 
SmplesizeAll = chkbox
SmpleSizePieces = txtbox
 
SmpleSizeAll is true in my test case, but the test keeps ending up at No
Sample Requested.
 
 
 
=IIf([SmpleSizeAll]<>0,"All
Pieces",IIf([SmpleSizePieces]<>0,[SmpleSizePieces],"No Sample Requested"))
 
TIA
 
Joe
