Need to fill form textbox with value from recordset

I have an edit page that populates a form from a recordset. One of the values has a quote symbol (")in it and it stops the entire value from displaying in the text box. Here is some code:

<% 
mSQL1 = "SELECT * FROM purchasing WHERE m_id = '" & Request.querystring("id") & "'"
Set rs1 = connectstr.Execute(mSQL1)

response.write rs1("m_comments")
response.write rs1("m_material")
%>

<form name="edit" method="post" action="request_edit_submit.asp?id=<%Response.Write rs1("m_id")%>">

<p><label for="txtMaterial">Material: </label><input type="text" name="txtMaterial" id="txtMaterial" value="<% = rs1("m_material") %>"><span style="margin-left:10px; color: red;">*This field is required</span></p>
  
<p><label for="txtComments">Comments: </label><textarea style="margin-left:15px;" name="txtComments" id="txtComments" cols="45" rows="5" ><% = rs1("m_comments") %></textarea></p>
  
<p> <input type="submit" class="nomargin" name="submit" id="submit" value="Edit Request"></p>

</form>

Select allOpen in new window

So lets say the value in both the comments and the material is 1/2" steel. At the top of the page the response.write will display 1/2" steel twice. That is correct. But in the form the material textbox will display 1/2 and the comments will display 1/2" steel. Why does an input type="text" cut off the data but a  textarea not? How do I stop this from happening.
