Hide object based on current selection in a specific field

Hi,

I'm trying to hide a sheet object unless a single selection is made in a specific field.

If I have 3 fields: FieldA, FieldB and FieldC, I want to display an object if FieldB only has a single selection and hide the object if FieldB has 0 or 2+ selections. It does not matter what is selected in FieldB, only the quantity.

I am falling at the first hurdle which I think is to extract the selection for the field from the GetCurrentSelection() function. I came up with the following:

=TextBetween(GetCurrentSelections(),'FieldB: ',chr(13),)

This works providing FieldB is not the last selection, because the selections in the GetCurrentSelection are separated by a CR. But if FieldB is the last selection there is no CR at the end of the string.

If someone knows an easy way to do this I would be really pleased, otherwise I need to extract the field selection from the GetCurrentSelection() result in the following circumstances:

No FieldB selection

FieldA: 1,2,3

FieldC: A,B,C

Only FieldB selection:

FieldB: first, second, third

FieldB is the first selection:

FieldB: first, second, third

FieldC: A,B,C

FieldB is the last selection:

FieldA: 1,2,3

FieldC: A,B,C

I'm hoping there is an easy way to do this without a complicated nested if statement.

Thanks in advance.

I got this working with the following statement: If there is only 1 item selected in FieldB this returns the value of the selection in FieldB, otherwise it returns a 0. Surely there is a better, more elegant, faster performing way than this?

=If(if(substringcount(GetCurrentSelections(),'FieldB: ')=1,if(findoneof(TextBetween(GetCurrentSelections(),'FieldB: ',''),chr(13),)=0,TextBetween(GetCurrentSelections(),'FieldB: ',,),TextBetween(GetCurrentSelections(),'FieldB: ',chr(13),),),0)=0,0,If(if(substringcount(GetCurrentSelections(),'FieldB: ')=1,if(findoneof(TextBetween(GetCurrentSelections(),'FieldB: ',''),chr(13),)=0,TextBetween(GetCurrentSelections(),'FieldB: ',,),TextBetween(GetCurrentSelections(),'FieldB: ',chr(13),),),0)='-',0,if(findoneof(if(substringcount(GetCurrentSelections(),'FieldB: ')=1,if(findoneof(TextBetween(GetCurrentSelections(),'FieldB: ',''),chr(13),)=0,TextBetween(GetCurrentSelections(),'FieldB: ',,),TextBetween(GetCurrentSelections(),'FieldB: ',chr(13),),),0),chr(44),)>=1,0,if(substringcount(GetCurrentSelections(),'FieldB: ')=1,if(findoneof(TextBetween(GetCurrentSelections(),'FieldB: ',''),chr(13),)=0,TextBetween(GetCurrentSelections(),'FieldB: ',,),TextBetween(GetCurrentSelections(),'FieldB: ',chr(13),),),0))))

Thanks in advance.

How about this

=GetSelectedCount(FieldB) = 1

Spot on Sunny T - thanks.

I couldn't believe there wasn't an easy way of doing this. Guess I need to refine my search techniques!

Cheers
