Tooltip in Siebel Forms

Hi together

we have the request to display a tooltip in our form applets.

The idea is to display in this tooltip the value of an other fields of this BusComp. So we have to fields:

1. Classification with the length of 2 letters

2. Description with the value of 3-4 words (max. 30 characters)

So the first idea was entering a new Caption-String Override like

<label title="This is sample hover text">Account</label>

But we had no solution for entering a variable into the "title="

We tried many variants of these ideas:

<label title="[Customer Description]">Customer Classification</label>
<label title=[Customer Description]>Customer Classification</label>
