How to eliminate empty spaces

[Gilbert13]

Hi -

I use this calculation to display the value just if the variable have a value.  The problem is when the variable doesn't have a value the calculation add empty spaces to the result.

 

Case ( Length ( $i1 ) > 0 ; $i1 ) & ¶ & 

Case ( Length ( $i2 ) > 0 ; $i2 ) & ¶ &

Case ( Length ( $i3 ) > 0 ; $i3 ) & ¶ & 

Case ( Length ( $i4 ) > 0 ; $i4 ) & ¶ & 

Case ( Length ( $i5 ) > 0 ; $i5 ) & ¶ & 

 

If there is a better way to accomplish this I will appreciate your help.

Thanks

Case (

Length ( $i1 ) > 0 ; $i1  & ¶ & ;

Length ( $i2 ) > 0 ; $i2  & ¶ &

Length ( $i3 ) > 0 ; $i3  & ¶ & ;

Length ( $i4 ) > 0 ; $i4  & ¶ & ;

Length ( $i5 ) > 0 ; $i5  & ¶ & ;

""

No, that's not what happens. The calculation may add empty rows to the result, not spaces. This could be eliminated by moving the carriage returns inside the Case() function =

Case ( Length ( $i1 ) > 0 ; $i1 & ¶ ) &
Case ( Length ( $i2 ) > 0 ; $i2 & ¶ ) &
Case ( Length ( $i3 ) > 0 ; $i3 & ¶ ) &
Case ( Length ( $i4 ) > 0 ; $i4 & ¶ ) &
Case ( Length ( $i5 ) > 0 ; $i5 )

or doing something much more simple =

List ( $i1 ; $i2 ; $i3 ; $i5 ; $i5 )

A note on my previous post. The Case function will go in logical order. Once it finds a true statement, it won't evaluate the rest. My post is for one calculation field. If you want it to check each separate variable, you'd have to do each one individually, either by a separate calculation or a separate script step. 

 

Example:

 

Case (

Length ( $i1 ) > 0 ; $i1  & ¶ & ;

""

)

Case (

 Length ( $i2 ) > 0 ; $i2  & ¶ &

""

)

Case (

Length ( $i1 ) > 0 ; $i1  & ¶ & ;

""

)

 

That's an invalid expression (which BTW appears also at the end of OP's formula).

 

 

In addition, when using Case(), an empty default result is entirely redundant.

Hi - Reid

 

Thanks for reply to my topic.

I tried your suggestion but something is missing

Thank you both for your help ;-)

Thanks for the correction comment! I didn't realize empty result was not needed. Putting the ¶ inside the case function makes much more sense.
