Hello everyone,

I'm having a strange issue with one of my Labtalk program.

It's a loop over multiple sheets A1, A2, A3...Ahalfcyclenumber.
In every of these sheets they are three columns. If the column Ima is positive then I transform an other column - the first one - with the constant "capa". Capa is actually define on sheets where Ima is negative. Capa is the last value of the 1 column for Ima negative sheets.
( negative and positive sheets alternate)

however, it works fine until cycle 8. Then " capa = col(1)[numpoints]" it's always done considering the col(1) of the A8 sheet... I don't understand why. Anyone has an idea ?

here is the code.

loop(ii, 0, halfcyclenumber)
{ page.active$=A$(ii);
if ( col(Ima)[5]>0 )
{ mathtool iy1:=(col(1)) operator:=sub operand:=const const:=capa;
mathtool iy1:=(col(1)) operator:=mul operan:=const const:=-1;
}
else
{
if (col(Ima)[5]<0)
{
numpoints = wks.nrows;
capa = col(1)[numpoints];
}
else
{
}
};

Hi,

I think you’d better figure out how many worksheets in your workbook at first. Try the scripts below and make sure that there are more than 8 worksheets in your workbook.

Loop (num,1,page.nlayers)   
{
      type "layer number $(num)";
};

On the other hand, I don’t think the loop can start from 0 as your description. You may change it from 1 to halfcyclenumber if you want the loop over sheets A1, A2, A3...Ahalfcyclenumber.

In fact, Origin provides various tools to help you to debug your LabTalk scripts. I think you can find a way to debug your code on this page:

Hope it helps.
