Hi,
Macro {||&("t1:a1+t1:a2/t1:a3") }, {||&(t1:a1) } ,&("t1:a1") error : variable t1 does not exist ,how to to these ?

// At last ,found the low level mistake : local variable can't be excuted in macro
{||macrofield("t1:a1+t1:a2/t1:a3",t1) }

function macrofield(cstr,t0)
private t1
t1:=t0
return &cstr

Antonio,
xbrowse:
oCol:bStrData := {||&(ALLTRIM(odb3:cformula))}

Try oCol:bStrData := {||ALLTRIM(&(odb3:cformula))}

xbrowse:
1. oCol:bStrData := {||&("t1:a1")}
// or oCol:bStrData := {||&("t1:a1+t1:a2/t1:a3")}
run time error: vriable t1 does not exist

1. oCol:bStrData := {||t1:&("a1")}
   runs OK!
