title: sum amounts from editable fields to a computable field dynamically in Lotus Notes
body: <p>We have designed Lotus Notes forms, where we are displaying the data from the external system in a tabular format. In the tabular display we have editable fields, where user enters amount in these editable fields. Now we need to add the data from these editable fields and display in the totals field at the bottom dynamically.
  Could some one please help me in this regard with code.</p>
  
  <p>The current code:
  The current editable fields are with name:
  <code>PE_TOBEPOSTED</code>, <code>PE_TOBEPOSTED1</code>, <code>PE_TOBEPOSTED3</code> and the total field is <code>TOT_AMT</code>. So in the field value of TOT_AMT the following code is written </p>
  
  <pre><code>w_postd := @Left(PE_TOBEPOSTED;15); 
  w_postd := @ProperCase(@Name([CN];@Left(w_postd;15))); 
  w_postd1 := @Left(PE_TOBEPOSTED1;15); w_postd1 := @ProperCase(@Name([CN];@Left(w_postd1;15))); 
  
  TOT_AMT = w_postd + w_postd1 + w_postd2 
  </code></pre>
  
  <p>PS: I am just two weeks old in Lotus Notes development</p>
  
  <p>Thanks.</p>
