换成下面的就不行？


cbb1=trim(thisform.combo1.value)

LOCATE FOR allt(gb&c.dw)==allt(cbb1)

IF found()
report form grqz.frx to printer prompt preview for allt(gb&c.dw)==allt(cbb1)

else
=messagebox( "请返回!",48+0+0,"提示")
endi


[解决办法]
LOCATE FOR allt(gb&c.dw)==allt(cbb1)
&c中的c是一个变量 ？
VFP中c是保留字
使用宏替换时，如果后面还有字符，就要多加一个.，如：
ctext = "1"
thisform.text&ctext..value
[解决办法]
LOCATE FOR allt(gb&c..dw)==allt(cbb1)
[解决办法]
注意红色部分

cbb1=Trim(Thisform.combo1.DisplayValue)

Locate For Alltrim(gb&c..dw)==Alltrim(cbb1)

If Found()
Report Form grqz.frx To Printer Prompt Preview For Alltrim(gb&c..dw)==Alltrim(cbb1)
Else
=Messagebox( "请返回!",48+0+0,"提示")
Endif
