How to query the expression statistics data

[#1]

Hey guys,

I'm Chinese,English so poorly,I hope someone can know my question

The form have a input box (we can input two nums),and have a btn,we can use btn search the data from chart,and data is expression statistics .the expression is

if(rzxxcs <> '' and rzsxcs <> '',
if(Count (??ID) >= rzxxcs and count(??ID)<= rzsxcs,count(??ID)),
if(rzxxcs = '' and rzsxcs <> '',
if(count(??ID)<= rzsxcs,count(??ID)),
if(rzsxcs = '' and rzxxcs <> '',
if(Count (??ID) >= rzxxcs ,count(??ID)),
count(??ID)
)
)
)

How do it use vb script actions?

My plan:

1.define fourvariables : NUM_SX,NUM_XX,rzxxcs,rzsxcs

2.define the variables NUM_SX,NUM_XX to Input boxs

3.vb script action

' Create By KanGwei in 2010/10/26

' get the value of variable

function getVarValue(p_varname)
getVarValue=activeDocument.variables(p_varname).getContent.string
end function

' set the value to variable

sub setVarValue(p_varname,p_varvalue)
dim d_var
Set d_var=ActiveDocument.Variables(p_varname)
d_var.setContent p_varvalue,true
end sub

' Search action

sub s_dosearch

dim d_sx,d_xx

d_sx = getVarValue("NUM_SX")
d_xx = getVarValue("NUM_XX")

' ???? ?? ???? Error info
if d_sx < d_xx then
msgbox "????????????"
' All Passed?Do Search
elseif d_sx >= d_xx then
call setVarValue("rzxxcs" ,d_xx)
call setVarValue("rzsxcs" ,d_sx)
end if

end sub

Now ,I have two problems:

1.Do you have another method do it?(I hope you can give me a QVW)

2.After search,How to clear the variable in the expression ?

Thanks!!!

Why you need variables to define search criteria ? Can you explain the purpose of the expression ?
