    if(webView==nil) 
    { 

    webView =[[UIWebView alloc]initWithFrame:CGRectMake(100, 50, 700, 100)]; 
    [webView loadHTMLString:[text_Array objectAtIndex:indexPath.row] baseURL:nil]; 
    webView.backgroundColor=[UIColor clearColor]; 
    [cell.contentView addSubview:webView]; 
    webView.tag=indexPath.row+999; 

    int hideWeb=[[webHideArr objectAtIndex:indexPath.row]intValue]; 
    if(hideWeb==1) 
    { 
     webView.hidden=YES; 
    } 
    else   
    { 
     webView.hidden=NO; 
    } 
    } 
    } 

    -(void)reviewedCustomButtonClicked:(id)sender 
    { 
int irow=[sender tag]-222; 

UITableViewCell *Cell=(UITableViewCell*)[progressTableView cellForRowAtIndexPath: [NSIndexPath indexPathForRow:irow inSection:0]]; 

UIWebView *web=(UIWebView*)[Cell.contentView viewWithTag:irow+999]; 
isCustomReviewed=YES; 

[webHideArr removeAllObjects]; 
for(int h=0;h<[array count];h++) 
{ 
    [webHideArr addObject:@"0"]; 
} 

if([btn currentImage]!=[UIImage imageNamed:@"arrow_up.png"]) 
{ 
    [btn setImage:[UIImage imageNamed:@"arrow_up.png"] forState:UIControlStateNormal]; 
    web.hidden=YES; 
    [imgArr replaceObjectAtIndex:irow withObject:@"1"]; 
    [webHideArr replaceObjectAtIndex:irow withObject:@"1"]; 

} 
else 
{ 
    [btn setImage:[UIImage imageNamed:@"arrow_dwn.png"] forState:UIControlStateNormal]; 
    web.hidden=NO; 
    [imgArr replaceObjectAtIndex:irow withObject:@"0"];

} 

increseCellHeight=[sender tag]-222; 
decreaseCellHeight=[sender tag]-222; 
[progressTableView reloadData]; 
} 

     - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
    if(isCustomReviewed==YES) 
    { 
     if (indexPath.section == 0 && indexPath.row == increseCellHeight) 
     { 

      return 150; 
     } 
     else
