how to erase several characters in a cell? : <p>I would like to erase characters "(B)" in the code column, so then I could do "summarise" the 'stock_needed'. My data looks like this.</p>

<pre><code>  code   stock_need 
(B)1234    200          
(B)5678    240      
1234       700          
5678       200          
0123       200          
</code></pre>

<p>to be like this.</p>

<pre><code>code   stock_need 
1234       200          
5678       240      
1234       700          
5678       200          
0123       200  
</code></pre>

<p>How could these "(B)" erased? Thanx in advance</p>
