<br><font size=2 face="sans-serif">Yes I've seen you resolve this one before . . . wasn't it something like "if &Multi(index1) = ' ' " ? ? ?</font>

<br>
<br>
<br><font size=2><tt>Hello wuggers, <br>
I think I've got the perfect Friday afternoon problem for you: <br>
<br>
What is the best way to check for a blank multiline element? <br>
<br>
Using '&MULTI& EX' as the condition works fine if there are NO entries. However<br>
if the assignment comes from an attribute you will always get a single blank<br>
entry if the attribute has no value. Having an attribute which doesn't return<br>
anything if it fails will cause the WF to error with "Error when determining<br>
attribute 'FOO' of object instance '[BO.BAR.]". Checking if it's blank as per a<br>
single element ('&ELEMENT& =') doesn't work. <br>
<br>
Of course it's possible to work around, but it seems something that should be<br>
checkable in a simple condition, or even two OR'ed or AND'ed conds, but I can't<br>
seem to spot it. I've a feeling that I've encountered this before but memory<br>
fails....<br>
<br>
Inputs appreciated, <br>
Cheers & happy Friday<br>
