I placed an example below, of which I don't necessarily 'need' to work, but I don't like that I can't get it to work. :) I've attempted to use the ISNA function, but am having little success since I 

=IF(VLOOKUP(H3,Credit!H:J,3,FALSE)=(J3*-1),"Please Purge",IF(VLOOKUP(H3,Credit!H:J,3,FALSE)<(J3*-1),"Not enough Credit... research",IF(VLOOKUP(H3,Credit!H:J,3,FALSE)<(J3*-1),"Additional Credit…  Research","No Credit Exists")))

I really would like to have a response to each formula, am I using the wrong functions or the wrong format?

Thanks!

为避免多次重复 VLOOKUP 函数，您可以在这种情况下使用 SIGN 和 CHOOSE，如下所示

=CHOOSE(SIGN(VLOOKUP(H3,Credit!H:J,3,FALSE)+J3)+2,"Not enough Credit... research","Please Purge","Additional Credit… Research")

如果将 VLOOKUP 结果添加到 J3，您将得到一个负数、零或正数，SIGN 函数将分别返回 -1、0 或 1，然后添加 2 得到 1、2 或 3，因此我们可以使用 CHOOSE 函数将 1,2 或 3 转换为相关的文本值

如果在 Credit!H:H 中找不到 H3，该公式仍然会给出 #N/A 错误，因此为了避免使用 IFERROR 函数（假设 Excel 207 或更高版本），因此最终版本变为：

=IFERROR(CHOOSE(SIGN(VLOOKUP(H3,Credit!H:J,3,FALSE)+J3)+2,"Not enough Credit... research","Please Purge","Additional Credit… Research"),"No credit exists")

也许

=IF(ISNA(MATCH(H3,Credit!H:H,0)),"No Credit Exists",IF(VLOOKUP(H3,Credit!H:J,3,FALSE)=(J3*-1),"Please Purge",IF(VLOOKUP(H3,Credit!H:J,3,FALSE)<(J3*-1),"Not enough Credit... research","Additional Credit… Research")))

MATCH 部分在 Credit!H:H 中查找值 H3，如果不存在，则 ISNA 处理结果错误并返回“不存在信用”；其余的基本上只是对原始公式的调整
