How to draw this ester

Having a chemistry nightmare tonight. I've had a look at producing esters, and this example produces an ester (and HCl) from an alcohol and an acyl chloride. However the alcohol also has a aldehyde group so I'm struggling to draw it. Can anyone help? I'll draw a picture. I need to draw its skeletal structure.

Thank you so much for the quick reply!
What happened to the OH group on the acyl chloride?

It's still there. The left half of the ester is from the acyl chloride. It's the alcohol on the aldehyde that attacks and forms the ester linkage. Here's the mechanism:

Personally, I'd have used a pencil.
