从文本框值Microsoft Access 2007中查看组合框值

Question

我有一个表格（＆＃34;患者并发症＆＃34;），用户使用2个级联组合框（＆＃34; catcombo＆＃34;＆＃34; speccombo＆＃34;）将数据输入到表单。组合框从表中提取它们的值（＆＃34;并发症＆＃34;）。该表有一个并发症类别的字段（例如，感染，出血，机械）。第二个字段列出了特定的并发症（例如，如果并发症类别是＆＃34;出血＆＃34;，具体并发症可能是＆＃34; GI＆＃34;或＆＃34;其他＆＃34;）。组合框的输入被连接并放入表单上的文本字段中（＆＃34; Complication＆＃34;）。那部分工作正常。

我的表单有几个命令按钮，包括＆＃34;编辑＆＃34;并且＆＃34;保存＆＃34;命令按钮。因为我不希望用户与＆＃34;并发症＆＃34;在表单上的字段中，当＆＃34;编辑＆＃34;时，我的字段变得不可见。单击按钮。相反，2个组合框变得可见，并允许用户输入数据。当＆＃34;保存＆＃34;如果选择，则发生相反的情况。两个组合框变得不可见，并发症字段变得可见并锁定。

不幸的是，当＆＃34;编辑＆＃34;如果选中，则组合框可见，但显示为空白（未选择或显示任何内容）。我试图让框显示给文本字段的输入。例如，如果文本字段显示＆＃34;出血，其他＆＃34;，我希望catcombo框显示＆＃34;出血＆＃34;和speccombo框显示＆＃34;其他＆＃34;。我一直无法找到任何效果。如果有人有任何想法，将不胜感激。

相关代码包含在下面。如果我能提供进一步的说明，请告诉我。
