I have a small table, and I changed the format of one of the columns from text to decimal (in order to sort properly), and now the table just displays the red triangle and "an error occurred/Unhandled error loading module".  The event viewer says" InnerException: Input string was not in a correct format."

I can't edit the table settings or delete the module.  Do I have to export all the other modules and delete the entire page? 

I went ahead and did the latter.  For what it's worth, the problem arose when I filled a table with values, and went back and changed the format for a column from text to decimal (after I realized the sort function didn't work as I wanted). The data was all decimal looking values, but apparently not in the right format.  If it had been a large table, it would have been a serious loss.  Seems like the exception could be handled a little less drastically?  Or the format should be unchangealbe after entry has begun?
