DTS Package Import Of HTM And Column Type Manipulation

I built a DTS Import Package to import an HTM file and it went smooth as silk. Replaced the file with another HTM Table of the same name and whammo a text field turned into an integer file and data goes missing. The first 20 or so rows of a particular column were all numbers. I tried to do a disconnected edit to alter the Source column to a string but the Edit button just disappears without changing the column's type value. The only way I can think of getting around this is to use something archiac like EDLIN to add a new table row at the top of the HTM Table with values to force the specified type. Anyone think of a better solution?
