Result of macro not displaying in Cell but does display in Function Wizard

[evileyeball]

Hello Libre Office.

I’m having a bit of a fun time here. This is my first foray into Macros in Libreoffice
I found a page online with a macro someone had built to find House words data of of a wiki page about a song of Ice and Fire and have modified the code they had for my attempt at fetching Magic The Gathering Prices

I have the following function

Public Function FETCHPRICE(sSet as String, sCard as String) as string

   
   sURL = "http://mtggoldfish.com/index/" & sSet & "#paper"
   dim sWords as String
   oSimpleFileAccess = createUNOService ("com.sun.star.ucb.SimpleFileAccess")
   oInpDataStream = createUNOService ("com.sun.star.io.TextInputStream")
   on error goto NoCardFound
   oInpDataStream.setInputStream(oSimpleFileAccess.openFileRead(sUrl))
   on error goto NoCardFound
   dim delimiters() as long
   sContent = oInpDataStream.readString(delimiters(), false)

   lStartPos = instr(1, sContent, "" )
   if lStartPos = 0 then
     Msgbox("Table Not found")
     FETCHPRICE = "-1.0"
     exit function
   end if   
   lEndPos = instr(lStartPos, sContent, "

") sTable = mid(sContent, lStartPos, lEndPos-lStartPos + 8) lStartPos = instr(1, sTable, sCard ) if lStartPos = 0 then Msgbox("Card " & sCard & " Not Found for Set " & sSet) FETCHPRICE = "-1.0" exit function end if lEndPos = instr(lStartPos, sTable, "") sRow = mid(sTable, lStartPos, lEndPos-lStartPos + 5) oTextSearch = CreateUnoService("com.sun.star.util.TextSearch") oOptions = CreateUnoStruct("com.sun.star.util.SearchOptions") oOptions.algorithmType = com.sun.star.util.SearchAlgorithms.REGEXP oOptions.searchString = "" oTextSearch.setOptions(oOptions) oFound = oTextSearch.searchForward(sRow, 0, Len(sRow)) If oFound.subRegExpressions = 0 then FETCHPRICE = "-1.0" exit function end if lStartPos = oFound.endOffset(0) + 1 lEndPos = instr(lStartPos, sRow, "") sPrice = mid(sRow, lStartPos, lEndPos-lStartPos) FETCHPRICE = sPrice exit function NoCardFound: Msgbox "Error Finding Card" FETCHPRICE = "-1.0" End Function

When I run it with Known values Like
=FETCHPRICE(“RAV”,“Circu, Dimir Lobotomist”)
it either Errors (which I assume is a result of me hitting thier page too frequently and in future revisions I can correct for)
or it Gives me back a BLANK CELL
I’ve inserted Breakpoints and put a watch on the sPrice Variable which is indeed a string variable with the correct price value in it when it is returns

Now the strange part is

When I open the Fuction wizard and enter the function it shows in the result window the correct resulting price.
Click OK in there to make the formula insert into the cell and it Either gives me “Error Finding Card” or gives me a Blank cell

I tried several things to remedy this
such as Returning “” & sPrice

Changing the function so it returns Double (and changing the “-1.0” returns to -1.0
But that didn’t work because when I tried to cDbl(sPrice) it didn’t like it It said Invalid Procedure call
I saw that Cdbl to go from String to Double needs to be cDbl(“12345”) format so I tried making it cdbl("""" & sPrice & “”"")

to concatinate some "'s around it
But no dice

I tried setting sPrice to "Price is: " & sPrice on the line before I returned it but no dice I get "Price is: "

When I alter the function so that the return value is a hard coded string It returns fine
When I return sPrice & “KAKAW”
I get “KAKAW” in the cell

But in all cases my Function wizard displays things like
Price is: 2.30
2.30 KAKAW
2.30
etc etc depending on which one of my failed fixes is or is not applied
yet the cell itself will not display the 2.30

As well we know from my breakpoints and watches (and from Msgbox(sPrice)) that sPrice is indeed containing the value 2.30 which is the correct price for “Circu, Dimir Lobotomist” as of this posting

I’m stumped
Any help you have would be appreciated as google has failed me.

I figured out what the problem was. What I thought was “2.30” was really “chr(10)2.30chr(10)”
stripping off the first and last character of the string which were newline characters made it display properly.

I’ve changed the code now so it returns double values and the -1.0 values are getting changed to be different so I can tell where it errored (as a card’s price should never be negative negative values make for a good error code)
