Fileread problem

For now i have an explicit problem.

In my main script i call this function at descriptionInit

Function ReadAllDesc

Var /global j

${foreach} $j 0 $secCount + 1

  SectionGetText $h $4

  ${StrContains} $5 "++" $4

  ${ifnot} $5 == ""

    StrCpy $5 $4 "" 2

  ${else}

    StrCpy $5 $4

  ${endif}

  !insertmacro DESC_READ $4 $lang $5

${next}

FunctionEnd

the macro has followed code in it:

!macro DESC_READ addonText lang addonVar

FileOpen $6 "$TEMP\addonInstallerPreFolder\5.1\${addonText}_${lang}.txt" r

FileRead $6 $${addonVar}

FileClose $6

!macroend

my problem is now, that when i insert instat of $4 and $5 the explicit Names i can compile my script but when i want to use $5/$4 i got an error in my FileRead line

"Usage: FileRead $(user_var: handle input) $(user_var: text output) [maxlen]"

can anyone help me with that? Do i hae a logical problem or do it didnt work.

$${addonVar} is not correct.

But when i swap for example

$4 with extension and $5 with ext then it works correctly. That is the thing what it is confusing me. My example is also guarantee to appear in my variable option in ReadAllDesc

The second FileRead parameter must be a variable, otherwise you get that compiler error.

Before i redesign my code in this Way i had $${addonVar} also and it worked well. in ${addonVar} is the name of an global Variable. And before i must do some changes(that the addon name has an other name as the Variable because of a leading ++ i had the same code but only 2 input parameter. And there it worked and when im got fixed names in the innput it worked too.
